David Cameron did not breach regulations by saying twat and pissed off on Christian O'Connell's Absolute Radio show, Ofcom has ruled.
The Conservative leader apologised after as he explained to Absolute Radio presenter Christian O'Connell why he did not use the Twitter social networking service.
During the interview, Cameron was asked whether he used Twitter, and he replied: The trouble with Twitter, the instantness of it - too many twits might make a twat.
Shortly afterwards, the Tory leader was talking about the impact of the expenses scandal on Westminster's reputation and said: The public are rightly, I think, pissed off - sorry I can't say that in the morning - angry with politicians.
The incident prompted 20 complaints about offensive language to Ofcom, but the broadcasting watchdog said the show was not in breach of its rules.
An Ofcom spokesman said: In the context of the interview and the programme overall, the remarks did not breach the broadcasting code.
