Russian tycoon Alexander Lebedev has attacked a fellow businessman during the pre-recording of a talk show on the economic crisis for TV channel NTV.

Mr Lebedev, a former KGB agent who own UK newspapers the Independent and Evening Standard, lashed out at Sergei Polonsky several times, knocking him from his chair.

Yekaterina Gordeyeva, NTV reporter and one of the talk show hosts, said that such a incident was not anticipated, but that "if the oligarchs are fighting, then it means... the crisis is a really worrying issue."
