Starmer was an incompetent prime minister, but I think the three-figure majority actually makes party management harder, not easier, because you have a bunch of MPs who are not going to be ministers and who will think 'I'm not here for a long time OR a good time'.

If Starmer goes he'll be the only PM who's party has a three-figure majority to be forced out by his own party. Historic incompetence
(Tory majority in 1990 had fallen below 100 due to by-election losses)
(Chamberlain was forced out by Labour refusing to serve under him. Stayed Tory leader)
