Britain may already be at war with Russia, former head of MI5 says

Eliza Manningham-Buller points to extent of cyber-attacks and other hostile activity orchestrated by Moscow

Britain may already be at war with Russia because of the depth and intensity of cyber-attacks, sabotage and other hostile activity orchestrated by Moscow against the UK, according to a former head of MI5.

Eliza Manningham-Buller, who led the domestic spy agency two decades ago, said she agreed with comments made by the Russia expert Fiona Hill, who argued in a Guardian interview earlier this year that Moscow was at war with the west.
