This weekend marks two years since Boris Johnson’s spectacular general election victory, but after a politically catastrophic seven days in Downing Street, there are now serious questions over whether he’ll make it to the next one.

With relations with his MPs at rock bottom, leadership threats of Theresa May proportions and a banana skin by-election this week hanging over him, some aren’t even sure he’ll last a year. 

His supporters point to Johnson’s ability to defy political gravity, but there’s an increasing sense that the latest set of scandals, including allegations of Christmas parties in Downing Street while the rest of the country was forced to stay at home, allegations of lying over Number 10’s redecoration, and a botched attempt at reforming parliamentary standards to get ally Owen Paterson off the hook, might now put that to the test. 

Critics suggest the handling of the Paterson case kicked off Johnson’s current ills by inadvertently sparking a discourse about lobbying, second jobs and probity in public life.

The baffling ‘Peppa Pig speech’ to a conference of business leaders last month also led to questions about Johnson’s competence, and he has since managed to upset both wings of his party with further tax rises and a controversial update to social care funding.

But it is his chaotic handling of these problems, rather than the issues themselves, which has angered MPs the most.  

Two Tories told PoliticsHome they felt it was his “cack-handed” response to the Paterson row and then the Christmas party claims that has turned the tide.
