He doesn’t half talk a load of wibble.
And perhaps, just briefly, Theresa May’s arched eyebrow has betrayed that she agrees with us.
The ex-Prime Minister was spotted giving her successor some withering side-eye today in a House of Commons debate on Brexit .
She was sitting behind him and just to his right in the chamber as Boris Johnson took questions on the Brexit plan he has sent to the EU.
The Prime Minister said both he and Mrs May had been clear “many times” that the UK will not put “physical infrastructure at or near the border” with Northern Ireland.
She looked at him, grimly.
Then an MP heckled: “10 miles away?”
And with perfect timing, the camera cut back to Mrs May – who was still staring archly at Mr Johnson, and by this point, couldn’t look more in disbelief.
There’s a good reason for Theresa May to be sceptical.
A row has erupted over plans for Northern Ireland to share single market rules with the Republic – but customs rules with mainland Britain.
That will mean some checks on goods crossing both the Irish Sea, and the 310-mile land border.
Boris Johnson today tried to play down any hint of customs checks on the land border.
He told MPs: “Under no circumstances will the UK institute physical infrastructure at or near the border.”
Yet his own plans admitted there will be a “small number of physical checks” away from the border, “at traders’ premises or other points on the supply chain”.
Irish Premier Leo Varadkar today said Mr Johnson’s “reassuring” comments were “in contradiction” to his own Brexit plans.
Mr Varadkar added: “Our objective is very clear. We don’t want to see any customs posts between north and south.”
Theresa May has vowed to remain an MP and even been re-selected to fight her Maidenhead seat -breaking the tradition of other former PMs, who left Parliament after standing down.
So far she has only spoken once in a Parliamentary debate since leaving office – to support the Domestic Abuse Bill.
But she has often been spotted popping down to Parliament’s cafes, alone and bodyguard-free, to buy herself a sandwich.
