London taxi drivers will stage a third protest against a ban on using Olympic traffic lanes just hours out from the opening of the Games.
The drivers will protest at Hyde Park Corner seven hours before the official opening of ceremony.
The cabbies have already held two demonstrations, including one which brought traffic to a halt outside the Houses of Parliament in Westminster.
They argue that they should be able to use the lanes, which are available only to Olympics officials and athletes.
Scotland Yard said it had imposed conditions on the demonstration under the Public Order Act 1986 that meant it had to be held earlier than first planned.
