He won't be missed but in true Farage style he is stepping down as UKIP's leader for purely selfish and unprincipled reasons.
He claims it is to break with tradition, and convention, to stand against John Bercow at the next general election. Serious parties do not stand against the Speaker of the House of Commons.
Of course it has nothing to do with the inumerable scandals about his private life, his huge expense claims, sorry EU allowances, and where they went. You see, UKIP MEPs won't publish their details when screaming for MPs to do so.
Nothing to do with him squandering UKIP's golden opportunity since the 2004 success in the EU elections.
No Farage is doing it for Farage, either because he genuinely wants to fight Bercow, a battle he will obviously lose, or because there is another pile of manure about to rain down on UKIP, manure around Farage and his antics.
I'd bet on the manure personally if I did bet.
Of course a cynic might say he has secured five more years on the gavy train, his third five year term, so he can have a really, really good time now and just enjoy the fruits of his labour.
