Prime Minister David Cameron said he would not be giving a "running commentary on different people's tax affairs" as "that would be wrong". He was responding to ITV News Political Editor Tom Bradby who asked if he thought Gary Barlow's tax affairs were morally wrong.
Mr Cameron also said it was important to distinguish between tax avoidance and tax evasion: the latter being illegal. He said the government would support for HMRC to pursue individuals engaging in "aggressive tax avoidance."
Comedian Jimmy Carr has admitted he made a "terrible error of judgement" over his tax arrangements.
Jimmy Carr did not break the law, but he exemplifies the feeling that the rich live by different rules than the rest of us.
The Government has re-stated it will crack down on the shady world of tax avoidance. Laws to do so may now be fast-tracked.
