An estimated 22,500 police officers have marched in central London in a protest over pay.
Officers are angry that a 2.5% pay rise has been backdated to only 1 December for officers in England, Wales and Northern Ireland.
Prime Minister Gordon Brown said he would have liked to pay more but it was part of the "fight against inflation".
