Citroen UK has been reprimanded for a TV advert which used flashing images that triggered a seizure in one viewer, according to the Advertising Standards Authority.

The advert, shown on terrestrial and satellite channels, featured a new car and the word ‘Yes’ flashing around 304 times.

The ASA received 10 complaints about the flashing images, some of which said the ad had induced symptoms associated with photo-sensitive epilepsy, including a seizure.

The broadcasters said the advert had been cleared ahead of broadcast and had passed approval for its flashing images.

However the ASA consulted Ofcom, which found part of the advert in breach of its Flashing Images Guidance.
