UK-donated Challenger 2 tanks have been used by Ukraine as part of its surprise incursion into Russia, a UK source has confirmed. The Ministry of Defence is not officially commenting on what specific UK weapons are being used by Ukraine. However, following Kyiv’s incursion into Russian territory the department reiterated that Ukraine had “a clear right” to use UK-supplied weapons for “self defence against Russia’s illegal attacks”. The UK is one of the biggest donors of military aid to Ukraine, behind the US and Germany.
