Only if the savings to multinationals were passed on directly to the consumer.
Your argument about increased investment in the UK is a hypothetical one.
Can you cite any developed countries where corporation tax has been reduced to zero and has led to the sort of increases in investment and earnings along with the reduction in unemployment that you mention?
It is as hypothetical as the spending increases you were calling for leading to increased demand. In fact, less so.
To zero, no, unless you count the tax havens that have built financial services industries on the back of zero taxes and secrecy (I'm not advocating secrecy. I would have even more transparent corporate reporting laws than we have now).
I will offer you Ireland though, who cut their corporate tax rate to 12.5% and benefitted from reduced unemployment, though the straight-jacket of the Euro and letting their banks run riot was less wise. There is quite a lot of evidence to suggest that cuts in effective rates of corporate tax lead to increased demand and, in some economies (typically those with flexible labour markets), reduced unemployment.
