London 2012: G4S chief Nick Buckles 'right person' for job

The chief executive of security firm G4S has told MPs he is the "right person" to make sure the firm delivers Olympic security staff, despite its struggle to supply enough guards.

Nick Buckles made the comments to the Home Affairs Select Committee after 3,500 extra troops had to be deployed to meet the firm's shortfall.

Locog chairman Lord Coe said it was not for him to say if he should resign.

It has emerged police have also helped fill gaps left by GS4.
