Security arrangements for high-profile public figures including politicians and royals will be reviewed urgently after the killing of Ann Widdecombe and other recent events, Home Secretary Shabana Mahmood has said.
Police support will be expanded to include leaders of political parties who are not MPs, as well as peers, former MPs, former members of the devolved parliaments and political party spokespeople, she said.
The independent review, carried out by former national security adviser Sir Stephen Lovegrove, will look at how existing security is provided and whether funding and measures are being used effectively.
It will build on the work of Sir Robert Buckland, who is conducting a separate review into the murder of Sir David Amess, Ms Mahmood told the Commons.
Reform UK spokeswoman Miss Widdecombe, 78, died on July 8 after she was hit over the head with a hammer 21 times at her home in Haytor on Dartmoor, Devon.
Ms Mahmood said: “Those who enter public life do so to serve. Robust debate and criticism are part of the job. Threats, abuse and violence are not.
“An attack on any individual in public life is an attack on every one of us, and it is an attack on democracy itself.
“We owe it to those public servants we have tragically lost, and to everyone who believes in a fair and open country, to ensure those who serve receive the protection they deserve.”
