These Labour MPs suffer from exactly the same malaise that destroyed Labour in Scotland - a complete inability to see that their Blairite, pro-'free' market and anti-public sector politics has got right up the noses of a large segment of the electorate, a segment large enough to get them a majority in 2020. Like Scottish Labour they are completely oblivious to this fact. No doubt the special circumstances of the referendum hastened Labour's demise in Scotland, but they were in serious decline anyway because they allowed the SNP to move into, and occupy, a huge vacant space on the left of politics that they had created by sticking to unpopular centre right neoliberal politics.
How does this happen? Its almost certainly the result of the groupthink that afflicts most politicians in the EU and the wider western world, resulting in a belief system that only markets matter and that they can provide solutions to everything. As a Green Party member I ought to be celebrating the death-wish that Blairite MPs are embracing but I don't. We have to get the Tories out in 2020 and Labour are the only Party that can do it. I hope we will gain MPs but we need a strong opposition from Labour that offers real alternatives to the asset stripping of the public sector rather than a timid, watered-down version of Tory policy. If Labour MPs succeed in ousting Corbyn and continuing with 'business as usual' I expect the Labour Party in England and Wales to suffer the same decline as the Party did in Scotland.
