John Mason, SNP candidate: This SNP victory is not just a political earthquake, it is off the Richter scale. It is an epic win, and the tremors are being felt all the way to Downing Street.

"We have removed the dead hand of labour of Labour control. Labour MPs across Scotland will be quaking in their boots"

Margaret Curran, Labour candidate: “I’m in politics because I’m driven to tackle poverty, inequality and to liberate the people of Scotland and Great Britain from those great injustices and my commitment remains as strong as ever.”

Douglas Alexander, International Development Secretary and a close ally of Mr Brown: “If you want me to say it is a bad result, it is a bad result. It hurts us to lose a seat like Glasgow East and we want to win it back.”

SNP Westminster leader Angus Robertson: " People have had enough and Gordon Brown had better listen because at the next Westminster election the SNP is coming. "

Scottish Tory leader Annabel Goldie: “Labour is mired in failure."
