The important thing for Johnson is to have someone else to blame. If a withdrawal agreement isn’t signed before the end of October and he provokes the EU into refusing another extension, then he can blame them for the turbulence that ensues. If he finds himself obliged to seek and accept an extension, then he can paint himself as the standard-bearer of Brexit, having offered a harder deal than May’s, but with his hands tied by a sinister cabal of Europeans, parliamentarians and spider brooch-wearing judges. Johnson calculates that a clear history of confrontation will keep the bulk of Brexit Party votes behind him, and deliver the ‘People v. Parliament’ election he believes he can win.
