COTSWOLDS MP Geoffrey Clifton-Brown has said he is safe and well after today's suspected terror attack at the Houses of Parliament but he, along with all other MPs in Parliament, are confined to his office and have been told to lock the door and not emerge until given the all clear.

He said: "A vote had just been closed and I walked with my colleagues to Portcullis House, when a vast number of people told us all to 'run, run, run'.

"We ran to Portcullis House and I went to my office which faces on to Bridge Street.

"I didn't personally see what happened but my staff did, they said a man in an SUV was driving down Westminster Bridge trying to mow people down.

"He killed at least two people and must have severely injured more.

"He slammed his car into someone against the bridge and fled his vehicle.

"After running around the corner he attacked a police man with two knives.

"Another officer then shot the man, and we aren't sure whether he was killed.

"We're all very traumatised and upset but all safe and locked in my office."
