Percentage of English speaking population in UK is approx %97, the equivalent for the EU as a whole is approx %50, so no its not the same.
Regardless of SNP willingness to join the EU, it does beg the question, if a union between nations that have a lot in common is struggling. How will the EU endure in time.
Also, this is very important I feel. Today we are voting for the government, and they are accountable to the British public.
But the European parliament makes judgements that affects Britain deeply. These decisions are made by MEPs from across Europe. But with the exception of our own MEP's, they are not accountable to the British public.
To me this seems deeply un democratic.
