Spencer Percival

Tonight I attended a quiz after work. My only genuine contribution to my team's score was the correct answer to the following question:

Who was the only British Prime Minster to have been assassinated?
 
Spencer Percival was shot in the Commons' lobby in 1812 by a disgruntled merchant to whom the government had failed to pay the compensation he thought he was due. He was also, as far as I'm aware, Britain's only evangelical Christian Prime Minister. He may have been shot dead, but he will certainly have known where he was going thereafter.
