Former Foreign Secretary, Boris Johnson has been forced to apologise in the House of Commons.

The senior Conservative MP is one of the most beloved politicians in the country and favourite to replace Theresa May in a leadership election.

48 letters of no confidence could be submitted by the end of next week as the Prime Minister faces a crunch Commons vote on her deal. Losing a vote of no confidence would spark a potential leadership election against her and Boris.

Mr Johnson has a weekly column in the Daily Telegraph but failed to declare more than £50,000 in income to the House.

He said: “On a point of order, you would be aware my speaker that my committee on standards has today published a report on 9 payments, mainly unexpected foreign royalties which I’m very sorry to say were recorded late on the register of members interests. 

“I fully accept that the dealy was a breach of the Houses rules. Though I am grateful to the committee for recognising that there was no intention to mislead the House and that I’ve been completely transparent, I, therefore, offer the house a full and transparent apology.”

MPs are required to declare payments for any work carried out in addition to their duties as an MP, in the Register of Members’ Interests.

Ms Stone found that Mr Johnson’s registrations were late on four separate occasions, involving nine payments, “which suggested a lack of attention to, or regard for, the House’s requirements”.

“The committee concluded that Mr Johnson breached the rules of the House by failing to register remuneration within the required timetable on nine occasions,” the committee said in a report.
