With Monday's parade due to be waved off by Sir Steve Redgrave from the Ritz Hotel at 1.30pm, Mayor Ken Livingstone has called on firms to let staff take a late lunch break to enjoy the free event. A fleet of open-top buses, together with new double-deckers bearing the London 2012 logo, will head east along Piccadilly to Piccadilly Circus, south down Haymarket and along Pall Mall East into Trafalgar Square.
