The UK will provide £2.5bn of military aid to Ukraine over the coming year, Rishi Sunak has said - Britain’s largest annual commitment since Russia’s invasion.

The PM made the announcement during a rare visit to the country, where he will also sign a new agreement supporting its long-term security.

Officials said the package will provide Ukraine with long-range missiles, air defence and artillery shells.

Some £200m will be spent on drones, most of which will be UK-made.
