Comedian Jimmy Carr says he has made a "terrible error of judgement" over using a tax avoidance scheme and has pulled out of it.
Author and PR agent Mark Borkowski believes apologising was the "only thing he could do" and it was a "belated PR scramble".
In tough times, people "will put a microscope" on public figures, he told the Today programme.
Bruce Dessau of the Evening Standard said it was interesting that Jimmy Carr "listened to the power of social media".
He doesn't think it will ruin his career but it "might hang around a bit".
"If you're a satirist you've got to watch your step," he told John Humphrys, and you need to be "whiter than white" about your own tax arrangements.
