Westminster is on lockdown this afternoon after an attack on a police officer at the Houses of Parliament.

David Lidington MP, leader of the House of Commons, and around 200 MPs have been instructed to stay in the chamber in the aftermath of the incident.

Lidington has been keeping MPs updated - here is his statement in full:

"Colleagues will have appreciated that events have been moving rapidly and I want to emphasise that the knowledge that I have which is definite is so far very limited.

"What I am able to say to the House is that there has been a serious incident within the estate. It seems that a police officer has been stabbed; that the alleged assailant was shot by armed police.

"An air ambulance is attending the scene to remove the casualties. There are also reports of further violent incidents in the vicinity."
