BORIS JOHNSON should “just come clean” with the British people over his villa Mustique holiday, Labour demanded at the weekend.

The Prime Minister’s holiday to the private Caribbean island 16 months ago could have cost more than double the £15,000 he declared in the Commons register, the parliamentary standards watchdog found on Friday.

Commissioner for Standards Kathryn Stone said the bill for the luxury break had not been met by Tory donor David Ross as Mr Johnson has insisted.
