In a statement read to journalists, Mr Salmond said he was “immensely proud” of the hard-fought campaign that secured 45 per cent of the vote in Thursday’s referendum.
“I am also proud of the 85 per cent turnout in the referendum and the remarkable response of all of the people of Scotland who participated in this great democratic, constitutional debate and of course the manner in which they conducted themselves,” he said. “We now have the opportunity to hold Westminster’s feet to the fire on the vow that they have made to devolve further meaningful power to Scotland; this places Scotland in a very strong position.”
Mr Salmond said his decision to quit had been influenced by a telephone conversation he had with the Prime Minister David Cameron yesterday morning to discuss the issue of more powers for Holyrood.
