The hon. Gentleman mentioned—as did several members of the Scottish National party—the ability of his party to influence the 1974–79 Government. My predecessor as the hon. Member for Dundee, East, Mr. Wilson, made that point on a number of occasions. Equally, he made the point that the Labour Government between 1974 and 1979 were the worst Government Scotland has had in many a year. How does the SNP rationalise its ability to influence a Government who were the worst Government Scotland ever had?
