A sexist advert featuring a female tennis player holding a Tunnock's tea cake in place of a tennis ball at the top of her thigh has been banned over the likelihood of it causing serious offence.

The poster showed the player with her skirt raised at the hip and included the text: "Where do you keep yours?" and "Serve up a treat".

One person complained that the ad was offensive and irresponsible because it was sexist and objectified women.

Thomas Tunnock Ltd, trading as Tunnock's Tea Cakes, said the ad appeared on a poster site near the SEC Hydro in Glasgow to coincide with a charity tennis match in November 2017, and was created with a tennis audience in mind.

The company said the placement of the tea cake was a substitute to the normal placement of tennis balls, adding that it did not intend to offend anyone.

The Advertising Standards Authority (ASA) noted that the advert showed the woman's bare thigh exposed and her underwear clearly visible, and while it was placed opposite an arena hosting a tennis match, it bore no relevance to the advertised product.

It said: "We considered that although the image was only mildly sexual in nature, when combined with the phrase 'serve up a treat' it had the effect of objectifying women by using a woman's physical features to draw attention to the ad.

"In light of those factors, we concluded that the ad was likely to cause serious offence to some consumers and was socially irresponsible."
