Britain says security blunder will not mar Games

LONDON (Reuters) - Britain sought to reassure the world on Tuesday that a last-minute security blunder that forced it to call up thousands of extra troops for next week's Olympics Games would not compromise people's safety.

With 10 days to go until the start of the Games, an embarrassing shortage of security guards, fears over airport queues and London's creaking transport system have eclipsed an otherwise smooth run in to the world's biggest sporting event.
