to support sir david's family, and all of our sympathies are with them. i would also like to recognise the courage and professionalism of officers from essex police and paramedics for their response to the incident. as you know, last friday, sir david tragically died from serious injuries after being stabbed at a constituency surgery in leigh—on—sea. a man was arrested at the scene. since then, the met�*s counter terrorism command has led the investigation. a large team of detectives have been working around the clock to find out as much as we can about what happened and why. that work has included searches of a number of london addresses. our advanced forensics teams have analysed digital devices and carried out a painstaking review of cctv footage.
