Jo Cox is the third person to be attacked while working for her constituency surgery.
In 2000, the Liberal Democrat MP Nigel Jones was injured by a man wielding a 1 metre long sword. His political aide Andrew Pennington died of 11 stab wounds to the stomach, chest and back.
In 2010, the former Conservative government minister Stephen Timms suffered life threatening injuries when he was stabbed twice with a kitchen knife by an Islamic extremist.
Outside of their surgeries another three MPs have been killed in active duty. These include:
- Conservative MP Airey Neave, who was assassinated by a car bomb planted by the Irish National Liberation Army which detonated at the House of Commons in 1979.
- Conservative MP, Sir Anthony Berry in the 1984 Brighton bombing of the Conservative Party Conference by the provisional IRA.
- Conservative MP, Ian Gow, who was assassinated by an IRA bomb in 1990 which exploded under his car outside his home in east Sussex.
