"The funding will help to leverage the best of U.K. military expertise and defense production to ensure Ukraine's victory on the battlefield, including in critical areas like long-range missiles, air defense, artillery ammunition, and maritime security," the U.K. government wrote in a press release published on Jan.

U.K. Foreign Secretary David Cameron said earlier this month that support for Ukraine within the country is bipartisan and not as controversial as in the U.S. and that London is ready to help for many years to come.
