Sir Paul McCartney has criticised McDonald's after the fast food company unveiled a burger advert featuring the Beatles.

The advert has been used in Liverpool branches of the company to show the “contribtuion” the band made to the city's culture.

But a spokesperson for Sir Paul, a vegetarian, said it was “ridiculous and insulting” of the company to use the images.

“What sort of morons do McDonald’s think Beatles fans are?” Geoff Baker, who called for a boycott of the company, said.

A spokesperson for the People for the Ethical Treatment of Animal (PETA), which Sir Paul represents, also criticised the advert.

“He became a vegetarian after watching lambs play in a field outside his home and surely would not want anyone to use his likeness to help promote meat,” they told the Sun.

“We hope anyone who sees his picture on the wall will be reminded that he’s a vegetarian and skip the Big Mac for a veggie burger.”
