BORIS Johnson has been hit with a new sleaze investigation over his luxury holiday to Mustique.
The Parliamentary standards watchdog launched a fresh probe over who paid for the PM’s trip to Mustique with fiancée Carrie Symonds.
The couple jetted to the luxury island weeks after his stonking General Election win in 2019.
But a mystery remains over who paid for the £15,000 trip – with the PM initially saying it was a gift from Carphone Warehouse David Ross, who owns a villa on the island.
Mr Ross said the declaration was a “mistake” and he had only “facilitated” the trip.
However Standards Commission Kathryn Stone has stopped short of launching a probe into the redecoration of his Downing Street flat.
The PM and the Tory Party are already facing an Electoral Commission investigation, and two internal inquiries by Cabinet Secretary Simon Case and new standards chief Lord Geidt.
But the row failed to do damage to the Tories in last week’s local elections, where Mr Johnson trumpeted wins in Labour’s former heartlands.
The Mustique investigation makes the PM one of nine MPs currently being probed by the parliamentary commissioner.
An update to the Commons website confirms Mr Johnson is under investigation over the “registration of interests” about visits outside the UK.
