John Stevenson (Carlisle) (Con): If the SNP ever had control of tax credits, would it increase income tax to pay for them?

Ian Murray: Will the hon. Lady give way?
Dr Whiteford: Let me answer this question.
Nicola Sturgeon has made a clear commitment to mitigate the impact of the tax credit changes, but—like the Prime Minister—she is in the dark about the exact proposals. George seems to be still writing them on the back of an envelope. We are clear that it will not be possible to quantify them for two and a half weeks yet.
