The government has endorsed an independently-produced Strategic Defence Review, which calls for a more lethal, tech-driven army to counter emerging threats, including possible Russian aggression.

Britain, one of Ukraine's staunchest Western supporters, plans to learn from Kyiv's more than three-year fight against Russian invasion, during which drones have transformed the battlefield. The 473 million drone package is part of a broader military support initiative for Ukraine, the government said.

Defence Secretary, John Healey will make the announcement at a 50-nation Ukraine Defence Contact Group meeting in Brussels, co-hosted with Germany. "The UK is stepping up its support for Ukraine by delivering hundreds of thousands more drones this year and completing a major milestone in the delivery of critical artillery ammunition," Healey said in a statement ahead of the meeting.

In addition to the drone deliveries, Britain said it has completed the shipment of 140 000 artillery shells to Ukraine since January and will spend more on training Ukrainian troops.
