In three weeks' time, Ed Davey could be standing at the dispatch box as the leader of the opposition, Rishi Sunak could be on a plane to California having lost his seat and three-quarters of the cabinet out on the job hunt while more than 500 Labour MPs take their seats. There are no leadership chances for the seatless James Cleverly, Penny Mordaunt or Priti Patel.
