Portrait of a killer: how the Southport murders are part of a new pattern of violent terror - Governments have found themselves ill-equipped to deal with the emergent terror threat from young men acce

Katie Amess, whose father Sir David Amess was stabbed to death by a terrorist in 2021, said it is right that an inquiry has been opened into Southport, but her calls have been ignored

After a teenager admitted murdering three girls at a dance class, Keir Starmer said people were being radicalized into violence for its own sake and terrorism laws might need to change.

"It's going to take a long while for Southport to properly get its head around what's happened, and why it happened, and to move on from that. "It is going to be really prevalent in people's minds now until we get some answers.

Britain faces a new threat of terrorism from “extreme violence carried out by loners, misfits, young men in their bedrooms” following the Southport murders, the Prime Minister has said.

Sir Keir said it was "clearly wrong" Rudakubana was deemed not to meet the threshold for intervention from the Prevent programme, and the Southport victims' families had been failed. The prime minister said the Southport attack "must be a line in the sand" and "nothing will be off the table" in the public inquiry.
