POGS most of your above post @20:46 I find, with every respect, total nonsense. When Jeremy Corbyn became the elected Leader of the Parliamentary Labour Party, those who had not polled for him were left with three choices.
There were those who resigned their membership of the party but in carrying out that demonstrated they did not accept the well demonstrated internal democracy of the organisation. In doing that they most definitely did not deserve the respect of anyone, for they show that they are nothing else but "very poor losers" who only support democracy when it fits there views. In short, like a spoilt child, they throw all their toys out the pram and not wish to play further.
There were those such as kier Starmer and many others who undoubtedly would have wished to see a different leader elected but have remained in the party and upheld its structures and democracy and who now have the opportunity once again to shape the party in the image they wish to see through that same structure and democracy. He and those of similar attitude deserve and command the highest respect. In that, they may not gain the party they wish to see, but the image they wish for will be put to the ballot.
We then have seen for more than four years those who never accepted the Corbyn Democratic election and remained in the party only to have carried out a highly destructive campaign against Corbyn. That has, I believe, now broken the Parliamentary Labour Party to the extent it can never be once again the "broad church" that they say they desire. MPs who covertly record private meetings with the labour leader and then sell that recording for personal gain to an extream right-wing newspaper are the lowest form of political life and of human beings in general, along with all who would support such action.
