The UK has exposed 18 Russian spies and their units responsible for cyber-attacks in Britain and hacking one of the victims of the Salisbury poisonings, David Lammy, the foreign secretary, has said.

Announcing individual sanctions, Lammy said Russia had targeted media, telecoms providers, political and democratic institutions and energy infrastructure in the UK in recent years.
