With the “Bercow Bombshell” (BB), his statement to the house on March 18th, quoting Erskine May’s 1844 anthology of Commons’ customary laws and Standing Orders, that Theresa May can’t have an eternal Groundhog Day rotation resubmitting her Brexit Deal, it has become impossible for May to offer anything new to the EU summit of March 21st.
According to Laura Kuensberg (late BBC evening news, March 18th), that means the EU has no reason to grant May a short prolonging of article 50, making it inevitable that the EU leaders will propose a long prolongation; which would result in a much softer Brexit (the UK having to remain subject to more EU directives, procedures and institutions than under the May deal).
To predict the mood of that EU summit, one can quote the French journalist in Newsnight (March 18th), who indicated that Le Monde, on March 15th, lost hope of May rescuing her deal, saying “let’s get cracking, let’s make a do-able (prolongation) arrangement”. Earlier, Macron said on March 13th that “the solution lies entirely in London”, which must offer a reason for prolongation to make him consider that. The French mood looks unwilling to tolerate any more British “one more heave” pleas for a prolongation; and to start asking concessions.
