BBC News:- Conservative MP Sir David Amess has died after being stabbed at his constituency surgery in Essex.
Police said a 25-year-old man was arrested on suspicion of murder after the attack at a church in Leigh-on-Sea.
They said they recovered a knife and were not looking for anyone else in connection with the incident.
Prime Minister Boris Johnson said “our hearts are full of shock and sadness” at the loss of “one of the kindest” people in politics.
Sir David, 69, had been an MP since 1983 and was married with five children.
Mr Johnson said Sir David had an “outstanding record of passing laws to help the most vulnerable”.
Health Secretary Sajid Javid said he was “a great man, a great friend, and a great MP, killed while fulfilling his democratic role”.
Sir David, who represented Southend West, was holding a constituency surgery – where voters can meet their MP and discuss concerns – at Belfairs Methodist Church in Eastwood Road North.
Essex Police said they received reports of a stabbing shortly after 12:05 BST and found a man injured.
He was treated by emergency services but died at the scene.
Sir David is the second MP to be killed in the past five years, following the murder of Labour MP Jo Cox in 2016.
