MI5 chief Sir Ken McCallum has warned against fuelling Russian propaganda efforts after Andy Burnham revealed Moscow’s attempts to interfere in the 2016 Brexit referendum.

Sir Ken said Russian President Vladimir Putin’s online trolls will be “delighted” if the furore caused by the Prime Minister’s comments continues.
