Only once in the post-war era has a British political party won a fourth term in office, but that is what the Conservative party are attempting to do in this election. It’s a tall order, but Boris Johnson has a plan: to make it clear that his is a new government — offering change, not simply more of the same. ‘I have great respect for my predecessors, it goes without saying, great respect, but this is a new government and we have a new agenda and it will be a different agenda,’ he insists, when we meet in an aircraft hangar in the marginal seat of Norwich North. ‘This is not a continuity government. This is a new government, we have a very different approach. If we can get in with a working majority, we will have a transformative agenda for the country.

Ever since Boris Johnson became Prime Minister his opponents — both inside and outside his party — have been convinced that his ‘do or die’ pledge to have the UK out of the EU by 31 October would be his greatest vulnerability. ‘We’ll make him miss this deadline,’ they thought, ‘and his credibility will be shot.’ Brexit party voters would write him off as another blusterer from a Tory party unable to deliver. He seemed to think so too, repeatedly saying that ‘extension means extinction’. His enemies have now succeeded; the defeat of the government’s Brexit timetable in Tuesday night’s vote means it is near impossible for him to meet that pledge.

‘I’m going to stick ruthlessly to script,’ says Boris Johnson. ‘This is not the stage of the campaign when you innovate.’ He’s right to worry about the timing. The new Tory leader won’t be chosen for just over two weeks but the ballot papers go out this weekend. Boris is the odds-on favourite. This is the most important week of the campaign and he’s determined to come across as a serious, game-changing leader, not the loveable yet unreliable joker. The old Boris would mess up his hair before going on television. Today, when we meet in his House of Commons office, he quickly puts on a jacket — as if getting dressed for a job interview. He’s making a sales pitch.

After today’s Cabinet, ministers are no clearer about what Theresa May’s intentions are. ‘Reading tea leaves would be easier’, remarks one Secretary of State. This problem is demonstrated by the different messages those present took from the meeting. One Cabinet source said that May’s closing words about governing in the national interest ‘felt a bit like a farewell speech’. While another minister says that May ‘gave no impression of being off’. Part of the problem was that because May had to dash off for a phone call with Arlene Foster, the leader of the DUP, the meeting hadn’t drawn to its natural conclusion when it was brought to an end.
