Yes, a future SNP Government would increase it, decrease it, keep it the same and use the amount raised in an intelligent way. I know the hon. Gentleman thinks he has asked a really clever question, but we have just had the 2015 election and I am not going to write the 2016 manifesto today.
To answer a little more clearly, we have argued for targeted reductions in corporation tax in order to promote investment in key industries. We have highlighted for many years the relatively low private sector research and development spend in Scotland.
