Virtual No.10

Number 10 Downing Street has opened its famous front door to the public after more than 270 years, with a virtual tour for web users.
Visitors can look at rooms, find out historical information and click on objects such as paintings and furniture for extra details.

Tony Blair told the BBC the tour was "an excellent way of showing the tremendous history of this building".

Number 10 has been used as a home by prime ministers since the 1730s.
