Crisis after crisis from Greece to Calais and the Mediterranean have dented the Left's belief in a European future - but they show internationalism is needed more than ever

The agreement between Greece and its European creditors has sent ripples spreading outwards across the continent. Greece, despite its comprehensive referendum rejection of austerity, has nonetheless been forced to accept harsh terms and without debt relief will still face more trouble in the long run (Smith & Stewart, 2015).

That forced capitulation has dented the belief of the Left, and of the radical Left in particular, that it can challenge and overcome the dominant neoliberal austerian narrative. That feeling of powerlessness has clearly shaken the Left's commitment to a future in Europe - though there are those such as Caroline Lucas who are argue that reform, not surrender, of the EU is still the way forward.

In Spain, Podemos - the radical Left party seen as equivalent to Greece's Syriza - has suffered from a slump in the polls (Nixon, 2015), while the mainstream Left, across Europe, is stumbling. Even Denmark's Social Democratic government, under Helle Thorning-Schmidt, has fallen (BBC, 2015). That leaves just eight EU countries with Left-of-Centre governments (Nardelli & Arnett, 2015 - including Italy and France.

There are those who have begun to argue, in the UK, for a 'Lexit' campaign, focussing upon a Left-wing scepticism towards the European project (Jones, 2015) - on a campaign critical of 'European' austerity politics.

The trouble with that assessment is that it ignores how 'Europe', and its institutions, have simply been the vehicle, rather than the originator and pusher, of the neoliberal agenda (Chessum, 2015).

"European project has been used by capital, and national governments which represent that capital, to make the poor pay for the economic crisis, and to bring down left wing governments where they seek to prevent this. With European politics at a crossroads, it is vital that the British left focusses on the real task at hand – building a radical political alternative that can challenge these forces – and not just on building an obsession with fighting the super-structure of the European Union."

National, social and fiscal conservative governments have used their positions on the European Council - the assembled representatives of the EU member states - to roll out their austerian economic scheme (Lucas, 2015).

"With the European council made up of ministers from each member state, it often simply reflects the prevailing currents in European politics. The imposition of austerity in Greece – forcing a population to pay the price for a crisis they didn’t cause – is simply an extension of an economic logic that spans our continent."

Caroline Lucas has argued that simply lashing out the EU itself isn't enough and isn't directing the blame where it really lies (Lucas, 2015). Lucas argues that the aim should be, instead, to reform the Union.

Amongst Europe's mainstream Leftists too, there are still those who are arguing for more European integration. Pier Carlo Padoan, Italy’s finance minister, wants new movement towards EU political union to be seen as the solution to the problem of national conservative member-state governments using the EU to impose their terms on Greece (The Economist, 2015).

That 'stay and fight for reform' mentality has been also been picked up by anti-austerity Labour leadership candidate Jeremy Corbyn (Watt & Wintour, 2015). After being pressured to make his position clear on Europe, Corbyn said that Labour should work with European allies for reform.

In a Europe where the dehumanisation of migrants and refugees (Elgot & Taylor, 2015) and Far-Right rhetoric (Mudde, 2015) are on the rise, the answer cannot be to retreat. For the Left, walking away means giving up on internationalism and solidarity.

Instead, the priority must be to reclaim Europe. To reform its institutions, around internationalism and humanitarianism, and return to Europe a spirit of coordination and cooperation - an energy that desperately needs to felt, all across the continent, from Greece to Calais and the Mediterranean.

As Labour divisions fuel fears of a 1980s SDP-style split, it's worth noting that Tony Blair could have prevented this crisis

As, probably, a rather dramatic over reaction, it has been suggested that the election of Jeremy Corbyn as the new Labour leader could lead to a split in the party. His election to power representing the party's Left-wing, it is said, could lead to another breakaway akin to that of the Social Democratic Party (SDP) in the 1980s.

That split was led by Centre-Right, liberal and pro-European members of Labour, known as the Gang of Four - namely David Owen, Roy Jenkins, Shirley Williams and Bill Rodgers. That group left to form a new centre party, the SDP, in response to the rise of a Left-wing faction under Tony Benn and Michael Foot, when they found themselves unwilling to follow an overbearing Right-wing faction under Denis Healey.

The formation of the breakaway party almost saw Labour drop to third in the popular vote when the SDP, in their alliance (which later became a merger) with the Liberals, took 25% of the vote in 1983. But there was a time when such a split may not have been so bad of a thing for the Labour Party, for socialists, for trade unionists or for British politics.

In the 1990s, Tony Blair came to power in the Labour party and began his 'modernising' project. So strong was his position, he was able to rewrite fundamental elements of the party constitution to allow himself greater freedom of means in achieving the party's democratic socialist ends - his so-called Clause IV Moment.

At its peak, Blair's 'Third Way' New Labour held 418 seats in the House of Commons, had the support of the Liberal Democrats and benefited from the defection of a good number of moderate Conservatives. Only a few steps shy of completing this project, Blair stopped short. Blair could have created a new, broad, Centre party - a UK Democratic Party - that might have absorbed Tory and Labour moderates alike into a new, more progressive, establishment party. Instead, he left Labour in no man's land.

Labour have become a party of professional, pro-establishment, besuited politicians, who won't give up their connections trade unions and Left-wing politics even as they preaches Right-wing economics to an electorate turned cold. The hypocrisy inherent in falling short of a full transformation, by trying to have it both ways, has seen the party's idealistic Left-wing base fragment, scattering into a hundred different parties. The party is bleeding away its identity.

It does now seem as if progressives - of all stripes - may have been substantially better off had Blair, in fact, succeeded in his attempt to modernise the Labour Party into a moderate, centrist, democratic party. Not because Blair's professional Centrism offers a particular boon to progressive politics, but rather because the waters of the Labour Party's identity would not have become so muddy.

The socialists and trade unionists of Labour's left might have become a consolidated rump, a solid, united, party that could have kept together the various disparate socialist parties. It might have been a strong and idealistic voice, alongside Charles Kennedy's Liberal Democrats, to the Left of Blair's Centrist democrats - a loud progressive anchor, like Sinistra Ecologia Liberta in Italy, to the Left of their own Democrats, or as the SNP have sought to cast themselves.

Maybe Blair's democratic party would have had the courage to introduce proportional representation - ultimately reducing the Conservative to a Far-Right rump, powerless in the face of the support for the Centre and Left. Maybe there would not have been two elections with Labour scrambling ever Rightwards in their desperation to avoid losing power.

Blair's failure to follow through, along with his more controversial decisions, helped to lay the foundations of the Left's fragmentation. Left-leaning voters, who want to vote 'true to themselves' (Freedland, 2015), have found themselves disillusioned or cast adrift as first Labour and then the Lib Dems sought the Centre-ground in the hope of getting into power.

Yet the progressive parties can still recover. Labour remains the largest Left-leaning party and would need to be at the heart of any recovery. Labour's various factions, if they could work together under a new leader, would be the central pillar of Caroline Lucas' proposed progressive alliance for 2020 - which will likely be the best hope for the Left's election chances.

A pact would need to put electoral reform at the heart of its campaign and aim to confine the iniquities of the UK's political system - that force the creation of these alienating big tents that prevent truly representative elections - to the past. From that point on, the Left could be true to itself. There could be multiple parties, of socialists and liberals, greens and radicals, without each hurting the election chances of the other.

It might end the stifling of legitimate political voices, that denies voters the opportunity to make clear their priorities. The Left could still then work together in government, in the spirit of co-operation and consensus for the common good, to ensure that we do not again have a government of narrow interests ruling on just a third of the vote.

Labour's woes continue as the party splits over welfare cuts - where is their unifying idea?

The Labour Party is in the midst of an identity crisis. Two election defeats seem to have completely sapped the party of self-belief and bold ideas and now the party is divided over the merits of the Tory Chancellor's cuts (Perraudin, 2015).

Labour are struggling to come up with a convincing alternative narrative to the one George Osborne is using to bulldoze his way through the public sector. That struggle is pulling the party apart into distinct factions.

Yet a big internal squabble might actually be, in the end, rejuvenating.

The factions in that fight a pretty familiar. There is the New Labour mainstream - a majority of which seem to be more Brownite than Blairite, following the school of Gordon Brown, Alistair Darling, Ed Balls and Ed Miliband. These are the moderates and modernisers, represented by Andy Burnham and Yvette Cooper in the leadership race.

To the Right of the mainstream modernisers there is a faction that has gone under several names, Blue Labour and One Nation Labour in particular. This is the wing of the party, represented by Liz Kendall in the leadership race, that wants Labour to embrace working class conservatism, along with the Far-Right themes of anti-immigration and clampdowns on welfare.

It is also clear that there is a small but significant number of Labour MPs, at the moment with Jeremy Corbyn as their ringleader, who are significantly to the Left of the Labour mainstream. They have stood here against welfare cuts here and Corbyn's leadership campaign has firmly embraced the broader anti-austerity movement.

How this division is healed will depend upon a lot of factors, internal and external to the party. But it is a state of affairs that must ultimately be settled. Labour's determination to be a big tent has largely suppressed or alienated voters on the Left, driving many of them away - particularly in Scotland.

If the moderate or Right-wing faction wins out, how much longer will its Left-wing remain bottled? If the Left-wing wins out, will the mainstream fall in line?

In the face of these issues, there are predictions that Labour faces an extended stay in the wilderness (Moss, 2015). One of the few ways back would encompass a major change of direction: embracing the proposed progressive pact in England and embracing electoral reform that can ensure representative government, showing that Labour is finally working to work co-operatively with others on the Left.

Yet for many progressives, who would have been taking hope from Caroline Lucas' progressive alliance proposal (Lucas, 2015), there will have been an ironically collective sigh of despair when Labour's tendency to give in to populism struck again - this time in the form of Harriet Harman (Wintour, 2015):

"We cannot simply say to the public: you were wrong..."

Why not? What exactly is the point of an opposition party, many on the Left will be asking, is if it isn't going to oppose?

If the party are just going to argue for the same policies as the Tories, differing only on who is better equipped to administer them, then are Labour and the Conservatives anything more than two squabbling factions of essentially the same party?

And if the party is just going to be a reflection of popular opinion, then does it even stand for anything? Where is the belief, the ideology, the theory?

That only produces an image of a Labour Party more interested in power than standing for something. It wants to build trust through sycophancy, not through ideas, theory, facts and reason.

While in the US, Bernie Sanders is proposing a push of support for trade unions, worker-owned co-operatives and the living wage (O'Hara, 2015), Labour are getting themselves in a political twist over whether or not to support Conservative cuts to welfare set to have a disastrous effect on the poorest (White, 2015).

Labour's next leader has to find a way to navigate these splits, these contradictions and the party's overall idealistic emptiness (Hawkins, 2015). There are internal rifts to heal and the Centre-Left of the political spectrum filled with alternatives to navigate. The leadership race itself, with its warts and all exposure of the party's factions is a helpful start in the process of reconciliation.

For the external matters, co-operation is surely Labour and the Left's best hope of opposing the Conservatives on big progressive issues like human rights and electoral reform. For the party's internal struggle, the answer can only be found by digging deep. By looking for the roots of what unites Labour supporters of all stripes and all those allied to the socialist and democratic movement.

To, humbly, get the ball rolling, here one word that offers a place to start: Justice.

Liberals have liberty. Greens have sustainability. With these words, and the ideas they represent, they can construct coherent tests for any policy. Labour seem to lost their connection to a simple and fundamental idea that would underwrite social democratic and democratic socialist analysis, and so their ability to construct a meaningful and consistent narrative.

The new leader of the Labour Party, to be announced in September, has to reclaim a unifying idea - like Justice - if they are to lead the party back out of the fractious wilderness.
