I cant see any justification for the SNP or Plaid Cymru being included in the National TV debates. They only put up candidates in one of the four countries in the U.K.
Particularily when the Northern Irish parties were specifically excluded from the debates.
The national debt is now £1.5 trillion or thereabouts, so I think Cameron / Osbornes claims of having gone a long way to sorting out the mess is a bit rich.
Obviously if the two Ed,s got into power things would be a hell of a lot worse though.
Re Cameron,s promise of an EU referendum - its not the first time he has promised that.
He is a compulsive liar, even by the standards of Westminster.
I believe Cameron is indeed scared, but it isn't Milliband hes scared of. Hence insisting the one real debate is a seven way debate. Thus ensuring no-one in particular will have much time to say anything at all.
