Can't disagree with you. I don't think Mayor Andy Burnham will be the next leader, perhaps the one after that in a year or two or more. However he is not eligible, as he is not a sitting MP.
The Tories would be scared of Burnham, less scared of Mayor
Sadiq Khan Mayor of London who will also be available before the next General Election in 2024, if a vacant seat crops up. Incidentally Labour will lose a third of its funding from central funds. Funding is based on how many MP,s your Party has. Therefore the huge fall will further diminish Labour's standing.
I'm hearing on the grapevine the Tories could put forward a motion of 'No Confidence' in the current Leader of the Opposition. If passed, Corbyn would lose the title and extra salary. He would remain an MP, just not on the Front Bench.
eileenusher Johnsons being put there by his far right supporters,
Boris was elected by the whole Tory Party because he's a winner, twice as London Mayor (a Labour City) and now as PM, he has attracted Labour votes from Mining and Steel working families of many generations past.
Voters like him, that is why Boris got 45% share of the vote. Labour got 32.2% and the poorly led SNP got just 3.9% of the vote.
