“I am devastated that we have lost Sir David Amess. David was not only a fellow Essex MP, but a kind and loyal friend.
“David served the people of Southend with endless passion, energy and integrity. That he was killed while going about his constituency duties is heart breaking beyond words. It represents a senseless attack on democracy itself.
“Questions are rightly being asked about the safety of our country’s elected representatives and I will provide updates in due course.
“My heartfelt thoughts and prayers are with David’s family and friends.”
