”The biggest concern has always got to be a safe and secure Games,” Cameron told a press
conference at the Olympic Park in east London.

“That matters more than anything else.”

”I think we’ve made as many preparations as we can, I think we have very good contingency
plans in place,” he said.

“Always as prime minister I feel that is an area I should take personal responsibility for,” he added.

London’s security preparations had been called into question in comments by Republican
candidate Romney, who is in London to attend the opening ceremony today.

Romney said several issues in the build-up to the Games had been “disconcerting”, focusing
on a fiasco involving private security contractor G4S which has failed to provide the number
of private guards it had promised.

A security force of more than 40,000 military and civilian personnel, backed by a huge
intelligence operation, is being deployed to protect venues, athletes and millions of
visitors.

The PM has called it the largest security operation in Britain’s peacetime history.
