The talks schedule to take place in Latvia later this week, Ms Truss is expected to emphasise her vision of a “network of liberty”, and caution allies to push back against Russia and Belarus’ attempts at destabilisation.

Ms Truss has outlined ahead of the meet: “We want a world where freedom and democracy don’t just survive, they thrive. To this end, we will stand with our fellow democracies against Russia’s malign activity.”

She went on: “We have seen this playbook from the Kremlin before when Russia falsely claimed its illegal annexation of Crimea was a response to Nato aggression. Nato is an alliance forged on the principle of defence, not provocation. Any suggestion that Nato is provoking the Russians is clearly false.

“Any action by Russia to undermine the freedom and democracy that our partners enjoy would be a strategic mistake.”
