A submariner who sank an Argentinian battleship during the Falklands War says he is proud of what he and his crew mates did.

More than 300 men died when the Belgrano cruiser was torpedoed by British forces during the conflict.

Bull Budding, who lives in Thurso, fired three missiles, two of which sank the naval ship.

Speaking on the 30th anniversary of the sinking, he says he remains behind the decision to defend the Falklands and thinks the Royal Navy would mobilise if Argentina invaded the islands again.

The 67-year-old says he was not due to fire the torpedoes, and had been scheduled to leave the Conquerer submarine. He was asked to stay board, and a technical fault meant he ended up pulling a lever to fire the missiles from the loading bay.

Mr Budding says he felt an initial surge of excitement as he heard the explosions, quickly followed by sorrow for the huge loss of life.

The sinking of the cruiser has been mired in controversy over the years and questions raised over whether it was inside the 200-mile exclusion zone around the Falklands, and if it was sailing away from conflict instead of towards it.
