The man accused of fatally stabbing the Southend West MP Sir David Amess is due to appear in court today (Tuesday, December 21) to enter a plea.

Ali Harbi Ali is charged with murdering Sir David during a constituency surgery in Leigh-on-Sea.

The 25-year-old is also charged with preparing acts of terrorism between May 1 2019 and September 28 this year.

On the morning of October 15 this year, Ali travelled by train from his home in Kentish Town, north London, to attend Sir David’s surgery at Belfairs Methodist Church, it is claimed.

During the meeting, he allegedly produced a large knife from his pocket and repeatedly stabbed Sir David.
