Who was Sir David Amess?
A Conservative backbencher for nearly forty years, the 69-year-old father of five entered Parliament in 1983 as the MP for Basildon.
He achieved totemic status within the Tory party for holding the seat in 1992, but switched to nearby Southend West at the 1997 election.
Raised as a Roman Catholic, he was known politically as a social conservative and as a prominent campaigner against abortion and on animal welfare issues.
He was also known for his championing of Southend, including a long-running campaign to win city status for the town.
