A Royal Navy warship was SLOTXO "sticking up for our values" in an incident with Russian forces in disputed waters around Crimea, Boris Johnson has said. The prime minister said the UK does not recognise Russia's annexation of Crimea and was pursuing freedom of navigation in international waters. Mr Johnson denied UK relations with Russia were at an all-time low. He refused to be drawn on whether he had personally authorised the HMS Defender voyage. But the prime minister said it was "wholly appropriate to use international waters" to "take the shortest route between two points and that's what we did". It was "very important" countries around the world continue to carry out manoeuvres "sticking up for our values, sticking up for what we believe in," he said on a visit to an Army barracks in Aldershot, Hampshire. This would include "democracy, human rights, equalities and the rule of law, and freedom of navigation," Mr Johnson added. On Wednesday more than 20 Russian aircraft and two coastguard ships shadowed HMS Defender as it was sailing off the coast of Crimea. Moscow's defence ministry said a patrol ship fired warning shots and a jet dropped bombs in the Royal Naval ship's path.
