If they don't offer it, they shouldn't complain when support for UKIP starts going through the roof because the Tories would have lied. Didn't Cameron offer us something special before and then it never materialised?
Yes, they did - they promised a referendum on the Lisborn Treaty but then decided, because it had already been passed they wouldn't. Of course Labour also broke their promise on this one as well. And let's not forget the Tories statement about THAT bill .... 'we won't be paying it' .... well they did but just a little late.
