(CNN) — For the third time in a little over a decade, British lawmakers stood up one-by-one in Parliament on Monday, paid tribute to a slain politician, and echoed each other’s fears about the rising tide of violence in politics.
“Politics is a calling for those of us here, but it should not be a dangerous one,” the country’s Home Secretary Shabana Mahmood said, as she sought to reassure Members of Parliament (MPs) of their security. “We must always be vigilant and respond to changing threats.”
The killing of former MP Ann Widdecombe last week, coming after the murders of sitting MPs Jo Cox and David Amess in 2016 and 2021, respectively, has reinforced that the last decade has been one of the most dangerous periods for UK politicians in the country’s history.
Not since “The Troubles,” the name used to describe the sectarian violence in Northern Ireland from the late 1960s until the Good Friday Agreement in 1998, have so many politicians been killed in a short period of time. During that time, four MPs were killed by Irish republican militants between 1979 and 1990.
Unlike then, however, there has been no active conflict within the country’s borders during this spate of violence. Police launched an investigation after Widdecombe, a former Conservative MP who then served as the immigration spokesperson for the right-wing populist Reform UK party, was found dead at her home last week having sustained “serious injuries.”
Police initially said there was no information to suggest her killing was politically motivated, before later announcing that counter-terrorism police were leading the investigation. A 28-year-old White, British man who has not been named was arrested, first on suspicion of murder, then on suspicion of “commission, preparation or instigation of acts of terrorism.”
On Tuesday, the force said Widdecombe had been killed in a “targeted attack.” They have not given any indication of the motive, but said one “line of enquiry” was whether the suspect was targeting Reform UK figures.
The murders of Cox and Amess were propelled by very different motives from each other. Cox, a member of the center-left Labour Party, was killed by a man who had extreme right-wing views and an extensive collection of Nazi memorabilia. Meanwhile, a “fanatical Islamist” inspired by Islamic State was found guilty of murdering Amess, who represented the center-right Conservatives. So instead of a unifying ideology driving this uptick in violence, as during the 1980s, these instances seem more disparate.
Alan Renwick, a politics professor at University College London and director of the college’s Constitution Unit, cautions against “making links between the very extreme actions of a small number of individuals and wider trends in society.”
Yet he acknowledges that the threat level faced by politicians has risen in recent years, raising alarm bells about the impact on British democracy
“At the same time, it is clear that MPs and others in public life are now facing numerous threats almost routinely,” he told CNN. “This is a change from the past, and it seriously impairs democracy.”
The annual number of crimes against MPs reported to the police hit almost 1,000 in 2025, almost doubling since 2022, the Times revealed in March. And that number marks a ten-fold increase from the 151 crimes reported by MPs in 2017,
