After a legislator was stabbed to death during a meeting with constituents, Interior Minister Priti Patel said on Sunday that the UK is investigating a number of solutions to improve the security of lawmakers.

The assassination of David Amess, a member of Prime Minister Boris Johnson’s Conservative Party, comes five years after the assassination of Jo Cox, a Labor Party legislator, and has sparked a reassessment of politicians’ security.

Amess, 69, was repeatedly knifed during a meeting in a church in Leigh-on-Sea, east of London, on Friday.

A 25-year-old British male was arrested on suspicion of murder at the scene, and police believe he acted alone.

“The speaker has already put in a range of measures post Friday as we have with policing,” Patel told Sky News.

“Within that there are other options that are being considered such as when you hold your surgeries, could you have officers or some kind of protection…?” she said.

Surgeries is the term given to meetings British lawmakers have with their constituents.
