Communications watchdog Ofcom has launched an investigation into whether the BBC breached broadcasting standards after a Conservative MP swore during a live TV show.

The investigation into a possible breach "of content standards" comes after former police minister Nick Herbert used the term "f***wit" while appearing as one of the guests on BBC2's Daily Politics programme.

He later defended his actions and pointed out that he used the term "disapprovingly".

Presenter Jo Coburn interrupted Mr Herbert, telling him "we won't have any more of that".

At the end of the programme - which was broadcast on BBC2 at noon -Ms Coburn offered a full apology for the MP's outburst, saying it was unacceptable and would not be repeated.
