I don’t see it quite like that Oreo, I think once you’ve been PM it’s very hard to continue to motivate yourself, watching things change that you have set up and believed in is profoundly dispiriting, and you need a new challenge, leaving the MP role clear for a new young enthusiastic MP to make their mark.
I agree with this, and the comments on this thread show that whatever Labour politicians do they will be accused of duplicity and dishonourable motives by the mind-readers amongst us.
In his position I would find it very difficult to hang on, and fully understand why he feels the need to move on. He has proved himself an excellent international statesman, and feel sure that he will do well in that role without his every move being sneered at and second guessed - that must be so dispiriting. I wish him well.
