Among Russia’s high command there is genuine gratitude for the British rescue effort. Without British help it’s clear the seven Russian submariners would have perished at the bottom of the Pacific Ocean.
    At an official reception the Defence Minister Sergei Ivanov presented Commander Ian Riches and two of his men with engraved Russian naval wristwatches. Mr Ivanov is now asking President Putin to give state honours to the British team. It was their Scorpio submersible, flown in from Prestwick that cut through the nets and cables entangling Russia’s mini-submarine.
    The seven Russians had been trapped inside for three days. Suffering from hypothermia and a lack of oxygen they’d appeared doomed. Commander Riches said when he saw the mini-submarine bob to the surface the feeling of elation was out of this world.
    Russia’ s government has ordered an investigation into why the submarine became trapped, and why Russia’s Navy couldn’t rescue its own men.
