Prime minister will use Hiroshima summit to push more neutral countries such as Brazil and India into doing more for Ukraine

The UK has unveiled a swathe of new sanctions against Russia, as Rishi Sunak arrived at the G7 summit in Japan with a self-declared mission to push India into showing greater support for Ukraine.

Flying into Hiroshima for the three-day gathering of world leaders – and becoming the first British prime minister to visit the city destroyed by a US atomic bomb in 1945, Sunak announced a UK ban on imports of Russian diamonds and Russian-origin copper, nickel and aluminium, with other G7 members expected to follow suit.
