Russia did try to interfere in Brexit referendum, head of MI5 confirms

Ken McCallum says Kremlin attempted to influence vote through social media and TV reports but it had little impact

Russia did try to interfere in the Brexit referendum through social media and television reports, the head of MI5 said on Tuesday, but he added that did not mean the Kremlin had any impact on the result.

Ken McCallum endorsed comments by Andy Burnham, who raised the issue over the past two days, though he said continuing to debate it had given the Kremlin a needless propaganda victory.
