Protesters invade Cabinet Office

Ms Kelly said the protesters were arrested and removed after a few minutes

Anti-war protesters managed to force their way past security and gain access to the Cabinet Office in Whitehall.

Ruth Kelly said three people managed to get into the building while a security guard was dealing with someone who was also trying to get in without a pass.

They accessed an office within the building, where they were found "within a few minutes" and police were called.

Cabinet Office Minister Ms Kelly says the incident happened last Tuesday and four people were subsequently arrested.
