Foreign Secretary, David Lammy, and his US counterpart, Antony Blinken, are in Kyiv today on a trip that Lammy has labelled “the first of its kind in a decade”, as the two countries seem to be on the cusp of granting Ukraine permission to use western weapons to strike deep inside Russia, writes Caitlin Allen. 

Their joint talks with President Zelensky come ahead of Starmer’s scheduled meeting with Biden at the White House on Friday, and a week after Ukraine suffered its deadliest attack of this year, after two Russian ballistic missiles killed at least 51 and injured at least 219 in the central-eastern city of Poltava.
