Rishi Sunak will call on world leaders to ensure a “lasting peace” for Ukraine with the establishment of a new Nato charter to help the country defend itself “again and again” in the face of any future declarations of war by Russia.

Fresh from hosting the Ukrainian president, Volodymyr Zelenskiy, in the UK last week, Sunak is expected to call for countries to “double down on our military support” and warn that “the security and sovereignty of every nation” is at stake.
