Washington bans Britain from sharing any U.S. military intelligence with Ukraine | 5 March 2025 | The United States has banned Britain from sharing intelligence from Washington with Ukraine as part of its withdrawal of support for Volodymyr Zelensky. Donald Trump's decision to freeze American military aid to Kyiv yesterday brought warnings that Ukraine could run out of weapons in as little as two to three months' time. But on top of missiles and ammunition, all UK intelligence agencies and military outlets also received an order expressly forbidding the sharing of U.S.-generated intelligence, previously known as "Rel UKR" -- short for "Releasable to Ukraine." The Mail has learned that the top-level security classification has now been removed by the United States pending further notification. The ban affects the likes of the UK's GCHQ, the spy agencies and intelligence branches of the Ministry of Defence.
