London elections: Boris and Ken in on-air tax row

London mayoral rivals Boris Johnson and Ken Livingstone have clashed over their tax affairs in an angry on-air row.

Mr Livingstone says claims he avoided some tax by being paid via a company were "smears". His rival had used "the same arrangement" when an MP, he said.

In an LBC radio phone-in, Mr Johnson called him "a barefaced liar" adding: "I always paid full income tax."

A furious Mr Johnson reportedly swore at his Labour rival as the row continued in a lift after the debate.

Liberal Democrat candidate Brian Paddick and Green candidate Jenny Jones were also involved in the debate.
