Yesterday was supposed to be Brexit day. Instead, the Government spent it trying to heave its Withdrawal Agreement over the line, with the threat that it could be this or no Brexit at all. They did their best; a few Tory sceptics were converted. Nevertheless, the deal died in the lobbies for a third time. Theresa May had told the 1922 Committee that she would resign if the Agreement passed. What will she do now that it has been beaten yet again? She cannot continue.
