Jan  - Britain will send 14 Challenger 2 tanks and other heavy weaponry to Ukraine in the coming weeks and will train Ukrainian forces to use the tanks and guns in the coming days, Prime Minister Rishi Sunak's office said in a statement late on Saturday.

"The Prime Minister is clear that a long and static war only serves Russia's ends," a government spokesperson said in a statement published on its website.

"That's why he and his ministers will be speaking to our allies across the world in the days and weeks ahead to ramp up pressure on (Russian President Vladimir) Putin and secure a better future for Ukraine."
