The Conservatives want to divide and rule- they achieved it with Corbyn, and think they can do it again.
If the 'far left' of the Party plays their game, Cons, despite the absolute mess Johnson and co have go us into- will win again.
The 'far left' of the Party has to come to terms that the only way to win, is to back Starmer 100%, and make clever alliances with others, Greens, Lib Dems, SNP, etc. In other countries with some form of proportional representation, the Left, Centre and Right can be split into all sorts of factions- but the reality of the First Past the Post system makes that impossible.
Even if, for some in LP, Starmer is not their ideal choice.
Personally, I think he is amazing, calm, very experienced and very well educated, always so well prepared, so calm and to the point. He makes Johnson look like a total idot in PMQT - totally unable to answer any questions and just go red and off on a shameful prepared rant and attack.
And anyone who buys his handicapped mum a donkey sanctuary will get my vote,
