British singer Robbie Williams has sparked fury among U.K. campaign groups by appearing to punch a pensioner in the music video for his latest release Candy.

The Take That star has been criticised by activists at the National Pensioners Convention (Npc) over the promo and for making jokes about the footage during an appearance on Britain's The Graham Norton Show on Friday (02Nov12).

During the Tv interview, Norton remarked on the controversial scene, ''That's quite a shocking image isn't it?'' to which Williams replied, ''It is, isn't it. They wanted me to kick a dog and I'm an animal lover, so I was just not having that. Then they said 'Punch a pensioner' and I was like, 'Yeah, I'm in.'"

Npc general secretary Dot Gibson says, ''Celebrities should think twice before making ageist comments which seem to imply that pensioners should be treated in a degrading way.

''Elder abuse is a serious issue and needs to be tackled rather than seen as a bit of a joke. We need to be uniting the generations, not suggesting that they are different. Pensioners are just young people who grew older.''

A representative for Williams says in a statement, ''Robbie Williams does not condone violence in any way; the plot for this particular video did involve some aggressive scenes but they in no way reflect his views on violence in real life. He was playing a particular role in the video."
