After tonight, the UKIP leader will have appeared 14 times on the programme since 2009 - more than any other politician.
UKIP’s unpopularity with Scottish voters is more evidence that Scotland and England are on separate political trajectories.
"I feel like such a fool. I see now that, far from being a chaotic rabble of whingeing narcissists whose only love of Britain is for its imaginary past, it’s actually a team of visionaries with a dynamic plan to serve the common good."
Support for UKIP surges to a record high of 22 per cent in the latest Survation poll, with the Tories down five points to 24 per cent.
It's right-wing bigotry that the protesters are "virulently opposed" to, not "the English".
UKIP is the British version of a Europe-wide rejection of mainstream, established politics.
With Cameron's party on 27% and Farage's on 17%, the gap between them is now smaller than the gap between Labour and the Tories.
The stubborn survival of Clegg may prove to be more significant than the noisy arrival of Farage.
The timing of the move is a political gift to Ed Miliband.
