Ukraine’s relationship with the UK has “got worse” since the Labour government took power in July, officials in Kyiv have told the Guardian, voicing frustration over Britain’s failure to supply additional long-range missiles.

The UK prime minister is yet to visit Ukraine four months after taking office and a frustrated Kyiv has said that a trip would be worthless unless Keir Starmer committed to replenishing stocks of the sought-after long-range Storm Shadow system.

“There’s no point in his coming as a tourist,” one senior figure in Volodymyr Zelenskyy’s administration said at a time when Ukraine is acutely concerned about the impact that Donald Trump’s US election victory will have on its war effort.

Ukraine is growing increasingly unhappy with London as Russian troops advance in the east of the country at their fastest rate since 2022, with US officials concluding that the frontlines can no longer be considered static. Ukrainian commanders said they were heavily outgunned.
