Problems in the world economy can stir up strong passions, but not usually in the course of a TV debate between Russian wealthy tycoons.

Alexander Lebedev, former KGB spy and owner of Britain's Evening Standard and The Independent, was on a short fuse during a forum on the issue.

After Sergei Polonsky, a fellow oligarch, said he was tired of "useless" discussions and would rather beat someone instead, Lebedev took him at his word and started punching.

Al Jazeera's Peter Sharp reports.
