The problem of the ‘New Party’ is a recurrent one but it is really only a problem because socialists insist that it has to be an exclusively socialist party.

It would be better to start with the model of a one member one vote coalition of democrats, socialists and liberals (even centrists), aiming never to get less than 51% of the popular vote, and then work back from that.

This might be a coalition to get electoral reform so that future coalitions might be formed from shifting components (including a democrat socialist one) or it could mean a single entity, analogous to a European Socialist Party, in which socialists have a leading role as pragmatic organisers of others.

Either would be infinitely preferable to the current situation of a federalised machine comprised of a very few special interest groups (including the political wing of the trades union movement) supporting a machine for a rather dim self-recruiting political class – which is precisely what we now have.

The reason John McDonnell is doomed to failure is because his plans can never really be much more than the capture of a bit of the State through a tribal political formation that is in terminal decline unless it reforms along the lines I have suggested – while the structured belief system of him and his followers results in them going pale at the thought of necessary compromises, not compromises of value but compromise even of tactic and rhetoric.

The bottom line is that the 1996 Partnership in Power reforms meant precisely what Alan has suggested – you cannot get anywhere without the patronage of the machine and that machine is only ever going to grant access in extreme conditions where it is likely to be losing power in the country. The Left is thus in a lose/lose situation by remaining within the machine. It either is apparently influential when power is slipping away or marginalised as access to power grows.

Best re-think everything and take the necessary twenty years (actually, I would say fifteen) to get it right …

I’m guessing that would require a few too many compromises, but the stars won’t ever be closer in alignment to winkle a splinter into the gap than now.

Building a new party up from the ground could take twenty years, if not more. The party would lack funds, a ready pool of activists, a significant platform in the press or experience in local government. Even accepting that voters continued to vote for those MPs who broke away, they’d be limited in number, and vulnerable to the more established Labour. In that time it took to establish the party, the very problems which the break-aways sought to challenge would essentially reign unchecked. Hardly a positive shift.

This is always assuming the new party would ever get off the ground. There’s little evidence that it would do, I fear. Non-Labour socialists have been trying to build a new worker’s party for years – and every time they’ve tried, it’s died in a glut of splitting and internecine fighting. Even if the ex-Labour activists managed to hold it together, there’s a strong chance that groups like the SWP would enter the party and, voting en-bloc, destroy it in much the same fashion as they did Socialist Alliance.

Forming a new party might well be useless, in the short term especially. Finding somewhere else might be just as difficult; where would they go? Virtually every non-Labour, purely socialist party is a basket-case. Beyond that pit of internecine viciousness, the Greens would take them, I imagine, but even that’s a limited group in terms of media access and funding at present. It’s a more attractive prospect than working all the way from scratch, for sure, but still possibly ineffective.

I’d argue differently if there was a prospect that some of the unions might break away with the Labour leftists. That’d tackle the problems of organisation and funding, up to a point. But until then, any attempts to foster socialism outside of the Labour party are likey to be slower outside than in. Getting onto Labour’s platform might be difficult; creating a new one would be even more so.

I don’t think the Labour Left realistically believe the Party as a whole is ever likely to adopt their policy programme but being Labour MPs gives them a position to advocate Left positions at a national level.
