Spencer Perceval is the only British prime minister to have been assassinated, having been shot on 11 May 1812 by John Bellingham, a merchant who blamed the government for his debt. From 1882 to 1990, six MPs were assassinated by Irish nationalists. The murder of Jo Cox on 16 June 2016 was committed by a white supremacist; Cox was both the first female and the first Labour MP to be assassinated. The latest incident, the murder of Sir David Amess on 15 October 2021, was committed by an Islamic terrorist.
Spencer Perceval was a British statesman and barrister who served as Prime Minister of the United Kingdom from October 1809 until his assassination in May 1812.

His Majesty's Prison Belmarsh is a Category A men's prison in Thamesmead, southeast London, England. The prison is used for high-profile cases, particularly those concerning national security. Within the grounds is the High Security Unit (HSU), which consists of 48 single cells. It is run by His Majesty's Prison Service. The prison has been called "Britain's Guantanamo Bay" due to the long-term detention of terrorism suspects without charge.
A political surgery, constituency surgery, constituency clinic, mobile office or sometimes advice surgery, in British and Irish politics, is a series of one-to-one meetings that a Member of Parliament (MP), Teachta Dála (TD) or other political officeholder may have with their constituents. At a surgery, constituents may raise issues of concern or request assistance in regard to local or national government matters. Often the constituent's issue will be followed up by a caseworker or assistant. Surgery meetings are usually confidential in contrast to town hall meetings, which are open to many people at the same time.
Batley and Spen is a constituency in the House of Commons of the UK Parliament. The current MP is Kim Leadbeater, a Labour politician, elected in a 2021 by-election by a 323-vote margin. The seat has returned Labour MPs since the 1997 general election.
Southend West is a constituency in the House of Commons of the UK Parliament. The seat is currently held by Anna Firth who won the 2022 by-election, following the murder of the incumbent MP, David Amess.
Michael Joseph Patrick Kane is a British politician who has served as Member of Parliament (MP) for Wythenshawe and Sale East since 2014. He is a member of the Labour Party.

On 16 June 2016, Jo Cox, a British Labour Party politician and Member of Parliament (MP) for Batley and Spen, died after being shot and stabbed multiple times in Birstall, West Yorkshire. In November 2016, 53-year-old Thomas Alexander Mair was found guilty of her murder and other offences connected to the killing in an act of terrorism. The judge concluded that Mair wanted to advance white supremacy and exclusive nationalism most associated with Nazism and its modern forms. He was sentenced to life imprisonment with a whole life order.
Kim Michele Leadbeater is a British Labour Party politician who has served as Member of Parliament (MP) for Batley and Spen since 2021.
On 15 October 2021, David Amess, a British Conservative Party politician and Member of Parliament for Southend West, was fatally stabbed at a constituency surgery at Belfairs Methodist Church Hall in Leigh-on-Sea, Essex. His killer was Ali Harbi Ali, a British Islamic State sympathiser, who was arrested at the scene. Ali was convicted of murder and the preparation of terrorist acts in April 2022, and was sentenced to life imprisonment with a whole life order.
A by-election was held on 3 February 2022 in the parliamentary constituency of Southend West following the murder of the Conservative MP Sir David Amess on 15 October 2021. Amess had been the MP for the constituency since 1997, and previously represented the nearby seat of Basildon from 1983 to 1997. Similarly to the 2016 Batley and Spen by-election—held after Labour MP Jo Cox was murdered—the major opposition parties declined to stand out of respect for Amess. The Conservative candidate Anna Firth won the by-election with 86% of the vote, with a turnout of 24%. No other candidate reached the 5% threshold to save their election deposit.
Operation Bridger is a nationwide police protection security programme in the United Kingdom designed to offer Members of Parliament (MPs) access to extra security in their homes and constituency offices. It was established in 2016 in the wake of the murder of Labour MP Jo Cox, who was killed at a constituency surgery.
There is no doubt that this murder was done for the purpose of advancing a political, racial and ideological cause namely that of violent white supremacism and exclusive nationalism most associated with Nazism and its modern forms.
