Heineken has been forced to change its television commercials after regulator Ofcom ruled they put too much emphasis on the alcoholic strength of the beer.

The ads, starring Goodfellas actor Ray Liotta, were aimed at informing consumers that the abv of the beer had changed from 3.4% to 5%.

The company said it believed it was being responsible by communicating the new strength, but has produced a revised version of the advert which is now on air.
