Donald Trump has indicated that the US will announce a plan to sell Patriot air defence systems and other weapons to Ukraine later on Monday, amid growing White House exasperation with Russia’s refusal to agree to a ceasefire. “We will send them Patriots, which they desperately need,” Trump added, describing the impending announcement as “business for us”. Though Trump did not spell out exactly who would fund the purchases, it is expected to involve European countries. Last week the German chancellor, Friedrich Merz, said Berlin was “ready to acquire” additional Patriot systems. The president’s predecessor, Joe Biden, donated $67bn worth of weapons to Ukraine after Russia’s full-scale invasion in February 2022.
