How many votes would the SNP have obtained if they were standing across the UK, not in a country comprising less than a tenth of the total population of the whole UK?It would be interesting to allocate the perks/resources based on total votes cast rather than number of MPs. That way the Lib Dems would get better offices than the SNP, and more parliamentary time. The UKIP member could have a jewel-encrusted office and as much time as he wanted!
But I think your idea's essentially a good one. It would give the Lesser Breeds a clear impression of their lowly status within the imperial order of things.
