MI5 chief says Brexit result remains valid despite Russian interference claims

MI5 chief Sir Ken McCallum has said that the result of the 2016 Brexit referendum is not in question. He was responding to comments by Prime Minister Andy Burnham, who said Russia clearly interfered in the vote. McCallum confirmed that Russian interference did happen, but warned against exaggerating its effect on the outcome. He also said the debate could divide the country if handled badly. Burnham denied that he was calling the result illegitimate. Conservative leader Kemi Badenoch questioned how Burnham had described the interference. McCallum also confirmed that Russian hackers leaked information during the 2019 general election campaign.
