Speaking at the Times Tech Summit in London, Mr Martin will say: "I can't get into precise details of intelligence matter, but I can confirm that Russian interference, seen by the National Cyber Security Centre over the past year, has included attacks on the UK media, telecommunications and energy sectors."

The NCSC is "actively engaging" international partners, industry and civil society to tackle the threat, he will say.

Since its launch last year, the NCSC has blocked tens of millions of cyber attacks and responded to 590 incidents - including the WannaCry attack which hit the NHS.
