On 12 October 2026, the Home Office announced an independent review of the UK's protective security system, to be carried out by Sir Stephen Lovegrove. According to the department, the review will examine whether current arrangements are fit for purpose and whether those most at risk are adequately protected against terrorism, extremism, state threats, harassment and intimidation. It will cover high-profile individuals including royals, government ministers, MPs, locally elected representatives and other prominent figures, but will not assess individual cases.

Dedicated police support was also expanded to leaders of political parties who are not MPs, peers, former MPs, former members of the devolved parliaments and political party spokespeople. The review is to look at how security is provided, whether funding and measures are used effectively and proportionately, and how decisions can be made more consistently. It is to build on Sir Robert Buckland's separate review into the murder of Sir David Amess MP.

Citing the Electoral Commission, the Home Office said 55% of all candidates experienced some form of harassment and intimidation in May's local elections and the same proportion did so at the 2024 General Election. The Home Secretary, Shabana Mahmood, said threats, abuse and violence against people in public life were not acceptable.
