UK Prime Minister Keir Starmer vowed on Tuesday to "leave no stone unturned" to uncover failings in preventing the killings of three girls at a Taylor Swift-themed event, saying an inquiry could lead to a change in terrorism laws.

Starmer said the government must also answer “tough questions” about how authorities failed to stop a violence-obsessed teenager before he stabbed the girls to death in the seaside town of Southport in July.

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

Government sources have told the BBC that Rudakubana had been referred to the government's counter-terrorism Prevent programme several times prior to the attack in Southport over his general obsession with violence.
