Prime Minister Boris Johnson is being investigated by Parliament's standards watchdog over a £15,000 Caribbean holiday.
The Parliamentary Commissioner for Standards has revealed she is investigating the Prime Minister for a possible breach, reports The Mirror.
17 months ago Boris Johnson and Carrie Symonds took a trip to the island of Mustique.
Mr Johnson said at the time Tory donor David Ross, co-founder of Carphone Warehouse, funded the villa where he stayed with girlfriend Carrie Symonds.
But Mr Ross said he did not pay for the villa, he just helped arrange it with a phone call.
So it remains unclear who paid for the holiday.
The Commissioner today said she is investigating a "Registration of interest under Category 4 of the Guide to the rules [Visits outside the UK] in 2020".
She is examining whether Mr Johnson breached Paragraph 14 of the Code of Conduct for MPs.
That paragraph says: "Members shall fulfil conscientiously the requirements of the House in respect of the registration of interests in the Register of Members’ Financial Interests.
"They shall always be open and frank in drawing attention to any relevant interest in any proceeding of the House or its Committees, and in any communications with Ministers, Members, public officials or public office holders."
