This will have to be quick, being on the move.
If Hammond and traitors go to the LibDems, Kate Hoey goes to BP, Lib Dems would probably be the main party, seen by leftwingers and all others disliking Johnson and Farage as the fallback party.
If Boris called a GE, which I can’t see him doing under those circumstances but if he did – I see the numbers going LD a couple of percent ahead of BP, itself line ball with Labour tribalists, the Tories a long way behind, the rest nowhere. That’s just percentages.
More critical of course is seats. If MPs declare for another party in this game of musical seats, no by-elections, then Boris would have to go to the Queen.
Unless parliament is prorogued of course.
