A TV ad for chocolate bar Twix has been banned for encouraging unsafe driving.

The advert shows a man with flowing hair involved in a car chase and crash that results in his and an identical, caramel-coloured car sandwiched on top of each other, like a Twix.

Five complaints issued against the advert said it encouraged dangerous driving and was irresponsible.

Mars-Wrigley, who own Twix, argued that the ad had a "cinematic presentation" and was set in a "world that was absurd, fantastical and removed from reality", which Clearcast, the non-governmental organisation that approves adverts before broadcast, echoed.

But the watchdog the Advertising Standards Authority (ASA) ruled the ad "must not appear again" in its current form because it "condoned unsafe driving".
