Over 6,000 people attended and among the crowds were a plethora of special guests and VIPs including Prime Minster David Cameron, London Mayor Boris Johnson and Jacques Rogge, president of the International Olympic Committee (IOC).
The countdown, organised by Greater London Authority (GLA) in conjunction with Innovision event management company and Westminster Council, was televised live on BBC One. It saw David Cameron make a brief speech on the current planning and budgeting for the games, followed by dancing, live music from The Feeling and the unveiling of the 2012 medal designs by British artist David Watkins.
Dayo Adelugba, Showsec's head of security for the event, said, "It was very high-profile event which centred around ensuring the one hour live TV show went smoothly.
"People were arriving from 6pm with the show starting at 7pm, and we had to make sure everyone was in place. We searched each person who attended and despite the tight timeframe the ingress and egress went really well and there was a really safe vibe throughout."
Showsec provided 130 SIA licensed security staff and stewards, and five supervisors.
