"A strong Scottish Government with its own currency, with clear willpower and the economic freedom to act in the best interests of the country can ride out such storms with ease because the policies of such a government will be economically fundamentally sound and it will, because it has that currency, have the full range of measures it requires to implement them.  But Scotland without its own currency will be in the exact opposite position; it will be fundamentally economically weak, forever destined to run every aspect of its affairs with the sole goal of “keeping parity with the pound”.  What a sorry country that would be. The SNP has to be wise enough to reject such a prospect. I hope its membership is." Professor Richard Murphy.
