Olympics is UK's biggest pre-planned police op
According to the Metropolitan Police, around 12,500 officers are to be deployed daily during the Olympic Games in the UK's largest ever pre-planned policing operation.
Approximately 12,500 officers will be available during peak days and 9,500 of these will be on duty in London, as 52 police forces from around Britain provide officers for the operation which starts on 4 June until after completion of the Paralympic Games on 16 September.
National Olympic Security Coordinator Chris Allison said: "Every force is playing its part in delivering a fantastic summer of celebration.
"The summer of 2012 will be a busy and challenging time for the British police service but with confidence and pride I can say we have the officers we need to keep the Games and our wider communities safe and secure."
They will include specialist officers who are trained in search techniques, marine, public order and firearms, on call alongside mounted police, motorcycle escorts and dog units, although most of the officers on duty will be unarmed.
Working with the police and 16,000 private security guards and Special Officer volunteers, will be 13,500 security personnel from the MoD and armed forces, including MoD Police and Civil Nuclear Constabulary. The cost of the Olympics 40,000 strong security force - supported by a significant intelligence operation - is around £553m (€662m). However the total bill for the Home Office - which is set to pay for the costs of sending officers to the Games from other forces - wont be known until after the event.
