May as well abandon the leadership election and just disband the party
Putting out a manifesto was all a bit of a joke anyway - they were never going to win a general election - essentially they were a pressure group pretending to be a political party, and there is no need for them to exist once we are out of the EU.
We'll still need them, though, if the politicians at \Westminster decided to attempt to undermine democracy just because most of them were remainers.
