Counter-terror police have renewed an appeal for information into the mysterious death of a Russian dissident, hours before his inquest is due to resume. Head of the Met Police's counter-terrorism command Richard Smith said questions remain about the death businessman Nikolay Glushkov, 68, in New Malden, south-west London, three years ago. Police launched a murder investigation after the father-of-two and Kremlin critic was found apparently strangled at his home on March 12, 2018. It was a week after the Novichok poisoning of the former Russian double agent Sergei Skripal and his daughter Yulia in Salisbury. Mr Smith said he was keen to hear from residents of Clarence Avenue, where Mr Glushkov lived for two years, after sightings of a black van in the area at the time.
