David Cameron is pulling no punches now. The savagery with which he attacked Boris Johnson in his Commons statement betrayed his contempt for the mayor’s behaviour. He didn’t name Johnson once – but he didn’t need to.
After running through his now familiar arguments for remaining in the EU (“stronger, safer and better-off”), the Prime Minister turned to Johnson (sitting behind him on the backbenches). With brutal efficiency, he dismissed the mayor’s suggestion that the UK could vote to leave in order to secure improved terms as “for the birds”. There would, he said, be no “second renegotiation followed by a second referendum” on the ballot paper. In line with No.10’s briefing this morning, he vowed to immediately trigger Article 50 (which lead to irreversible withdrawal) if the UK voted Out (the Leave campaign insists this would not be the case).
