Thirty-one late-stage attack plots were disrupted over the past four years by intelligence officers, the director general of the MI5 has said.

MI5 director general Ken McCallum said that the threat of terrorism in the UK remains “a real and enduring thing” and warned that recent events in Afghanistan could lead to a new 9/11-style attack plot.

He added: “We do face a consistent global struggle to defeat extremism and to guard against terrorism - this is real problem.”

He told the BBC’s Today programme on Friday: “In the last four years, working with the police, my organisation has disrupted 31 late-stage attack plots in Great Britain.

“That number includes mainly Islamist attack plots but also a growing number of attack plots from right wing terrorists.”
