The government ordered an investigation Sunday after the newspaper the Sunday Times obtained documents outlining security arrangements at Prime Minister Tony Blair's private home, including a secret escape route in case of a terrorist attack.
The newspaper said a reporter paid a $20-fee to inspect house plans in the Sedgefield Council's public records office. The Blairs have a home in Trimdon Colliery, 250 miles north of London, in the Sedgefield parliamentary district that Blair represents in Parliament.
They now live at 10 Downing Street, the prime minister's official residence here.
The newspaper said the files showed the location of security cameras, types of locks and an escape route, and outlined security arrangements at a house next door that has been taken over as a police operations center.
The newspaper said the Home Office, which is responsible for police and security, has ordered the plans withdrawn from the public records and the government ordered an investigation into why the house plans were not kept secret.
