Britain faces a “new threat” of terrorism and extreme violence from “loners, misfits, young men in their bedrooms” following the Southport murders, Sir Keir Starmer has warned.

Last summer’s Southport killings will mark a “line in the sand” for Britain, Sir Keir Starmer has said, promising to introduce new terror laws if necessary.

British Prime Minister Keir Starmer said on Tuesday that the Southport knife attack last July was a sign that the country faces a new type of terrorism threat in the form of extreme violence perpetrated by loners.
