Raab was stinging in his criticism of the SNP's economic record
Dominic Raab, Tory candidate for Esher and Walton, was answering a financial question from the audience when he was interrupted by Màiri McAllan, an SNP candidate, who blamed austerity for the deficit.
Mr Raab said: “Until you have paid off the deficit you can’t get the debt down. We paid off £100billion. It shows you how important it is to not add to it.”

It follows the launch of the SNP manifesto that reiterated SNP demands for a referendum on Scottish independence once the final terms of the Brexit deal is negotiated.
