Keith says:

"That just does not stand up.
Labour put their own case and attacked the Tory case.
Labour, Lib Dems, SNP and UKIP and the broadcasters would expose any "scare-mongering and lies" of the Tories."

Except that they didn't. There were quite robust rebuttals, which were just not reported. The print media is entirely in the tories' pockets (including apparently the Guardian these days), the BBC is bound by a duty of impartiality (and completely hamstrung by tory complaints even when they are impartial), and Sky is owned by a far-right foreign demagogue. So the prevailing narrative was of fear that the Scottish would have undue influence, whereas the alternative, and far more justified narrative that the city of London has undue influence was suppressed. There is no independent press, the press and Sky/ITV do a more thorough job of pushing the tory viewpoint than Pravda ever did for the Soviet communist party.
