Highly-trained British agents have been in Pakistan working with authorities there to prevent security breaches during the Olympic Games in London, Downing Street has said.
The news came as the Sun reported that a crime ring in Pakistan was offering to provide fake passports and visas, as well as help smuggle bogus individuals into Olympic venues posing as members of athletes' support teams.
An undercover reporter was provided with a fake Pakistani passport for £600 and he was offered a UK visa and an official letter saying he was part of the Olympic squad's entourage for a further £7,000, which the newspaper suggested could provide an avenue for terrorists seeking to target the Games.
Asked about the report at a daily media briefing in Westminster, the Prime Minister's spokesman said: "My understanding is that we are confident that we have the checks in place and the arrangements in place to deal with these issues.
"The delegation lists for the Olympic Games are very tightly controlled and when it comes to Pakistan we have had highly-trained staff based in Pakistan dealing with the authorities there to deal with this."
