AJ's boss, Steve Fugill, 52, defended the extras by saying business on the van, on the A4303 south of Lutterworth, was slack at this time of year.

But former town mayor Cathy d'Ambrumenil said: "This is not the impression of our quiet market town we want people to receive."

Trading standards chiefs said the matter was being investigated.

The optional extras are displayed on the wall of the van.

During the past few months it has built up a steady stream of men and women splashing out on the saucy menu.

Mr Fugill, from Glen Parva, said he was determined to carry on despite needing to apply to the local district council for a special licence.

"At the end of the day, we are just trying to earn a living," he said.

"Our trade is slack at this time of year. This country is so far behind Europe, where you buy these things from a garage or a supermarket."

The 52-year-old added he stores the toys out of view during the school holidays.
