London's mayor was urged to intervene today in a dispute over Olympic pay which threatens to cause chaos in the capital on Friday because of a strike by bus workers.

More than 20,000 members of Unite are set to walk out for 24 hrs in support of a claim for a £500 bonus for working during the Games.

Len McCluskey, the union's general secretary, wrote to Boris Johnson today with a "final call" for a meeting to try to avert the strike.

He accused the mayor of wanting to "take on Unite", putting the success of the Olympic Games in "jeopardy" for politically-motivated reasons.
