BORIS JOHNSON has escaped with just a rap on the knuckles after failing to enter full details of his £15,000 Tory donor-funded holiday in the register of MPs’ financial interests.

The Prime Minister and his then fiancée Carrie Symonds jetted off to the Caribbean island of Mustique for a New Year getaway following the Tories’ election landslide in December 2019.

Questions were asked about how exactly Mr Johnson funded the luxury trip to the 1,400-acre private island.

Commons standards commissioner Kathryn Stone found that he had breached the MPs’ code of conduct by not “making sufficient inquiries to establish the full facts about the funding arrangements” for the trip.

The decision could have led to his suspension from the Commons, but MPs on the standards committee overuled Ms Stone today. 

Despite helping Mr Johnson avoid formal sanction, they did note that he had twice been reprimanded for “an over-casual attitude towards obeying the rules” and therefore “expected him to go the extra mile” to avoid any confusion this time. 

“It is regrettable that a full account and explanation of the funding arrangements for Mr Johnson’s holiday accommodation has only come to light [due to] our own enquiries, rather than at an earlier stage,” the committee added. 

“If greater clarity had been made available to the commissioner at the first instance, this matter could have been cleared up many months ago.”

The Prime Minister and Ms Symonds stayed on a villa on the island, part of St Vincent and the Grenadines, between Boxing Day 2019 and the following January 5.

The MPs’ register of interests stated that the cost of the accommodation was covered by Carphone Warehouse co-founder David Ross. The telephone tycoon initially said that this was incorrect but later issued a clarification saying that he had indeed “facilitated” the couple’s stay.
