Burger King has riled the Tories with an advert on the side of a London bus.

Mimicking the infamous line that the UK sends £350 million a week to the EU the ad says:

“Another Whopper on the side of a bus. Must be an election.”

Next to the slogan is Burger King’s Whopper.

The EU money claim – fronted by Prime Minister Boris Johnson – has been roundly dismissed by experts.

Some called it a “clear misuse” of official figures.

Mr Johnson was even threatened with court action over its veracity – but the case was dismissed by the High Court.

A Burger King spokesman said:

“As the Home of the Whopper, we felt that if anyone has the right to stick whoppers on the side of a bus, it’s us.

“So naturally, we’ve taken the opportunity to shine a light on our iconic Whopper in all its flame-grilled glory.”
