In 1979 a Mr Callaghan resigned after only managing to lead Labour to winning 269 seats in Westminster.
In 1992 a Mr Kinnock resigned after only managing to lead Labour to winning 271 seats in Westminster.
In 2017 a Mr Corbyn only managed to lead Labour to winning 262 seats in Westminster.
Despite winning less seats than Callaghan and Kinnock, Corbyn refuses to resign.
Indeed, he and his supporters indignantly demand that the leader of the party that won 56 more seats than him resign.
Such is the Corbyn power delusion.
