Dorset Police say they can't yet say how many extra officers will be deployed at the Olympics, to help plug a security gap left by G4S.

The county's one of nine forces sending hundreds of additional officers - after the private firm failed to find enough guards.

Meanwhile, Home Secretary Theresa May's told MPs in the Commons this afternoon that G4S repeatedly assured the government they would overshoot their recruitment targets - and only admitted they'd actually fallen short last week.
