The Conservative party have released an advert warning voters not to “bet” on Labour at the general election - amid two gambling scandals. The 19-second video was shared on social media on the same week that a police constable working as part of Rishi Sunak’s protection team was arrested over alleged bets made related to the timing of the vote. A statement from the Metropolitan Police said the officer was taken into custody on Monday 17 June on suspicion of misconduct in a public office and has since been bailed pending further inquiries. One of Rishi Sunak’s closest parliamentary aides, meanwhile, is facing also a Gambling Commission probe after he “put a flutter” on when the election would take place.
