Priti Patel said MPs were being asked to share their whereabouts with police as part of increasing their security.
Asked on Sky News’ Trevor Phillips On Sunday programme what security changes were likely to be seen, the Home Secretary said: “MPs have already been contacted by their local police forces, so that’s 600-plus MPs, around what are they doing, sharing information with police so police know where they are, checking their actual physical security.
“These are all the practical measures, basically.
“These are the one-on-one conversations that are taking place, and rightly so.
“But with that, we are making sure that Members of Parliament have the confidence to go around in their constituencies and having that advice from police and security about how to keep themselves safe.”
The Home Secretary said there were “immediate” security changes being offered to MPs in the wake of the killing of Southend West MP Sir David Amess.
The Home Secretary told Sky News’ Trevor Phillips On Sunday programme that, as well as an independent review into the anti-terror Prevent initiative, there were protection changes being readied.
“In terms of your immediate point around safety and security of individuals, there is a lot of work that has taken place already,” the Cabinet minister said.
“There is more work under way on Friday, yesterday, today and going forward with policing in constituencies but also with the parliamentary authorities around security of MPs.
“That is absolutely geared up, and I should emphasise this, around looking at this weekend, Members of Parliament are in their constituencies, next weekend they will be doing the same, out and about, and alongside that what are the protective measures we can put in immediately?
“This isn’t a case of, ‘let’s wait for two, three, four weeks’. These are immediate changes and measures that are actively being put in place and discussed with MPs.”
The Home Secretary has said the Prevent programme is being reviewed to ensure it is fit for purpose. The scheme aims to stop people becoming terrorists or supporting terrorism.
Asked about a review of the programme, Priti Patel told Sky News: “Prevent is going through an independent review right now. It’s timely to do that, we have to learn, we obviously constantly have to learn, not just from incidences that have taken place but how we can strengthen our programmes.”
She added: “We want to ensure that it is fit for purpose, robust, doing the right thing. But importantly learning lessons, always building upon what is working and addressing any gaps or issues where the system needs strengthening.”
It has an annual budget of around £40 million.
It was launched after public bodies were placed under a statutory duty in 2015 to stop people being drawn into terrorism.
