British Prime Minister Rishi Sunak on Saturday pledged to provide Challenger 2 tanks to Ukraine, making it the first Western country to supply the heavy tanks Kyiv has been calling for. The pledge saw a swift reaction from Russia which warned it would only “intensify” the conflict.

“Bringing tanks to the conflict zone, far from drawing the hostilities to a close, will only serve to intensify combat operations, generating more casualties, including among the civilian population”, the Russian embassy in the UK said. Sunak said the tanks were a sign of the UK’s “ambition to intensify our support to Ukraine”, according to a readout of a phone call with Ukrainian President Volodymyr Zelensky.

Ukraine’s European allies have sent Kyiv more than 300 modernised Soviet tanks since Russia invaded in February 2022. But they have so far held off on dispatching the Western-made heavy tanks that Ukraine has repeatedly requested to push forward against Russian invaders.

Zelensky thanked the UK on Twitter for making decisions that “will not only strengthen us on the battlefield, but also send the right signal to other partners”.



Ukraine’s forces have taken heavy losses in the battles of Soledar and Bakhmut in recent months and have called on the country’s allies to give it more support.

“To win this war, we need more military equipment, heavy equipment,” Andriy Yermak, head of Ukraine’s presidential office, said. Foreign Minister Dmytro Kuleba also said that he had spoken with US Secretary of State Antony Blinken and “emphasised the need” for Ukraine to receive Western-type tanks.

"The issue of heavy tanks has long been a key one for Kyiv and many experts see providing Ukraine with modern tanks as a vital building block in its ability to win against Russia. Germany has been especially hesitant of supplying heavy tanks".

The Prime Minister stressed that he and the whole UK Government would be working intensively with international partners to deliver rapidly the kind of support which will allow Ukraine to press their advantage, win this war and secure a lasting peace.

The UK announcement comes ahead of next week’s meeting of the Ukraine Defence Contact Group, which coordinates arms supplies to Kyiv, at Ramstein Air Base in Germany.
