Home Office make Olympics security vow
The Home Office has vowed that every safety and security effort would be taken to protect the Olympic Games from being interrupted by protesters.
Security at London 2012 is being overseen by the Home Office, who were given a first-hand warning of possible problems during Saturday's Boat Race on the River Thames.
A lone protester forced the race to be halted for half an hour by swimming into the path of the Oxford and Cambridge crews.
The incident raised immediate concerns about the forthcoming Olympics, where the public will line the route for the marathon, triathlon, road cycling and open water swimming.
British Olympic Association chairman Colin Moynihan admitted police and security chiefs could never completely eliminate the threat of "one idiot" disrupting events at London 2012.
But a Home Office spokesman said: "The focus of the Government and everyone involved is to deliver a safe and secure Olympic and Paralympic Games.
"We are working to a robust and comprehensive safety and security strategy. We want to reassure everyone that we will leave nothing to chance in our aim to deliver a Games that London, the UK and the whole world will enjoy."
Moynihan said Olympic security was under constant review but that it was difficult to stop individuals.
"It just takes, and is likely to be, one idiot," he said. "You can never completely remove it but you can do everything possible to protect the interests of the athletes by minimising it."
Boat Race organisers had been warned about potential protest swimmers ahead of last year's event but there was no information suggesting Saturday's race would be targeted.
