No it wouldn't , Farage is skilled in debating and educated... Brand is an idiot who made good in the media and youth driven culture. Farage would destroy him in a political debate.
Wishful thinking mate, Farge would pull out of QT if he's got any sense.
That would be the worst mistake of his politcal career IMO.
Better to turn up and rely on his pals in the media to spin it to look like he "won" even if he lost.
