Sir Nick will say: 'State-based competition is now being employed in more novel and increasingly integrated ways and we must be ready to deal with them. The threats we face are not thousands of miles away but are now on Europe's doorstep - we have seen how cyber warfare can be both waged on the battlefield and to disrupt normal people's lives.
"The threats we face are not thousands of miles away but are now on Europe's doorstep - we have seen how cyber warfare can be both waged on the battlefield and to disrupt normal people's lives - we in the United Kingdom are not immune from that", he will say on Monday (22 January). "The time to address these threats is now - we can not afford to sit back", he will say.
Gavin Williamson, the new defence secretary, is known to have rejected proposals such as slashing army numbers...
Lord Ricketts went on to warn the relationship was more vital than ever before in the face of "a more aggressive Russian Federation, the emergence of North Korea as a nuclear power and the uncertainties about the longer-term U.S. commitment to Nato following President Trump's hesitations over re-affirming article 5".
The Russian army conducted large scale military exercises a year ago, including simulated attacks across northern Europe, from Kaliningrad to Lithuania.
He will point to Syria where Russian Federation has very publicly demonstrated its long-range strike capability on numerous occasions.
Inevitably some commentators will also view the one-off speech as General Carter's vision should he become the next Chief of the Defence Staff - the position is expected to be announced in the coming months and the experienced soldier is one of the leading candidates.
Last year, prime minister Theresa May said Russian Federation had "mounted a sustained campaign of cyber espionage and disruption" against other nations.
This intervention from Carter is as much an appeal for more money to fund the armed forces and to avoid further cuts.
Carter will say the UK's ability to respond to threats will be eroded if it doesn't keep up with its adversaries, and he says the time to address these threats is now.
Mr Williamson is believed to have successfully argued that defence should be removed from the review so it can be given more time and consideration before decisions are made ahead of next Autumn's budget.
Since taking over from Sir Michael Fallon in November, Mr Williamson has fought on behalf of the Armed Forces and engaged in a row with the Chancellor Philip Hammond over spending.
