Newbury MP Richard Benyon was among MPs shut inside the main Parliamentary chamber for several hours.
Mr Benyon yesterday Tweeted he was among MPs locked inside Parliament following the attack in which the armed man attempted to enter the House of Commons.
Mr Benyon told NewburyToday that he had walked through the gate just minutes before the attack.
“I came in just a couple of minutes before it happened at that gate. I didn’t hear anything but others said that people jumped through the barriers and over the gate and attacked a policeman. Shots were fired and there’s a man down," he said.
“I’m sitting here in the chamber. We’re in lock down which usually means they are worried about someone still on the premises or a secondary attack; but everyone is very calm.”
Mr Benyon said that he told his staff to stay in his office and to wait for the all clear to be given.
"There’s about 400 people sat in the chamber and we are well protected but the parliamentary estate is a very big rambling area and there are lots of nooks and crannies. It will take quite some time I imagine,” he said.
