I have been quietly watching from the sides, as I have such mixed feelings about it all- and don't know what the answer is, at all. Actually I don't think anyone would say 'I know exactly what the LP should do now, and win'.
The world has changed- and peoples aspirations too. No longer do we have large groups of workers with a strong sense of community and common hardship and dreams - like the miners, workers for large manual corporations, ship workers, etc. Many are now house owners too, have a car, etc.
The massive problem is this antiquated First Past the Post System- so undemocratic as it leaves huge numbers without a vote that counts, because they happen to live in the 'wrong' area, eg not representative of their opinions and aspirations.
But it also leaves a LP which is made up of members and supporters from the 'sublime to the ridiculous' and everything in between. In other countries with some form of proportional system, this is not the case. Communists and socialist parties are separated, and there are also left wing parties which are much closer to centre. The LP just cannot function with such 'extremes', that have totally different aims and policies.
And it takes you right back to the realities of the FPTP system. A divided LP has NO chance to win. And a LP which has very LW goals and policies, nowadays, when the groups above have been dismantled and have very different hopes and dreams, just un-electable. We have seen it with Corbyn, and we will see it again if Momentum takes over. This is the reality, whether you believe Momentum and the 'extreme' left is the way to go or not. They will not take the majority of the Party with them, and they will not regain the trust of all those who voted Tory last time, for the first time ever.
I am a huge admirer of Ken Loach- his films have portrayed the extremely difficult lives of many- and I watched his films so many times. I also thought Corbyn was a great campaingner, and that he was deliberately tarred and his image destroyed in a disgusting way by the Tory Press.
So, what is Starmer to do with groups which are undermining the Party and ensuring that LP will not be electable, despite the disgusting and dreadful behaviour and policies of Johnson and his cabale - whose only interest is to stop them and their mates paying taxes?
First Past the Post is the reality, whether we like it or not- and a divided LP, once again, will never win an election.
A choice.
