Oh dear, oh dear. Would the SNP care to apologise in advance for getting its sums wrong on the £11 billion black hole at the heart of the Scottish budget? I will spell out the situation so that nobody is in any doubt. The spending commitments that the SNP has made in this session of Parliament amount to more than £4 billion a year. If that is not enough, we would lose the union dividend of £11 billion. I am inclined to be generous, but even on the most generous estimates, oil and gas revenues would not fill the gap. Basically, if we do the sums, they show that we are £11.9 billion short and that the cost to each household would be £5,000. Apologise for that, John Swinney.
