The Brexit lobby would do well to remember that he changed his position from remain to leave 4 months before the vote in 2016 ... he's well know for his reversals and his contradictions - I'd put a modest wager on him going to Europe ... and coming back with a 'no' - ie no change to the transition agreement (May's deal) but with some assurances on post transition trade and then arguing that 'having looked the Europeans straight in the eyes' he is now 'totally and unequivocally convinced' that the backstop won't come into force and asking parliament to pass the May deal ... with the alternative being a referendum on 'leave without a deal' or 'remain' or a General Election - both of which are totally antithetical to the hard exiteers.... time will tell ... he might even get out voted!
