Changing the driver of a runaway (Brexit) train which is speeding towards a broken down bridge over a chasm is going to do a lot of good. :(
Why not just stop the train?
Mrs. May point blank refuses to allow the British electorate the opportunity to change their minds, but she postponed the Parliamentary vote on her terrible deal, hoping that M.P.'s will change their minds, and now she's running around Europe trying to get EU bosses to change their minds!
She probably deserves to go now.
