About time tbh. As for the SNP/PC... it seems unnecessary to me. Whilst I'm sure they're terribly important in Scotland what's the point of broadcasting them to me in south Devon?
Do they even stand for seats that aren't in Scotland?
Unless of course there're separate debates in which case have one in Scotland with Lab/Con/UKIP/Green/SNP/Lib Dem, one in Wales with Lab/Con/UKIP/Green/P.C./Lib Dem, and one in England with the 5 multi-national parties.
