Games security 'not compromised':
The safety of London 2012 has not been compromised by the failure of private contractor G4S, the BBC is told by the Home Office's head of security.
G4S confirmed it could not meet its commitments only on 11 July, he said.
The opening ceremony for London 2012 is now just a week away, and will take place at 21:00 BST on Friday 27 July.
The Public and Commercial Services (PCS) union has announced that thousands of Home Office staff will strike for 24 hours next Thursday, when many thousands of visitors are due to arrive in the UK.
The action will include the UK Border Agency, Identity and Passport Service and Criminal Records Bureau.
The home secretary said the strike was "shameful" as it threatened disruption to people travelling to London for the Games.
