Boris Johnson under ANOTHER investigation over his £15,000 Christmas holiday to the Caribbean

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.

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.
