Captain Britannia: Nigel Farage is the Union's Useful Secret Weapon

Your enemy’s enemy is not necessarily your friend. That is something forgotten too easily. Nevertheless, though he may not be your friend he may, for a time at least, be your ally.

And so it came to pass that Nigel Farage is, for the time being, Labour’s new best chum. In Scotland, that is. The Tories are quite pleased with him too and, if anyone could find them, perhaps the Liberal Democrats would be too.

Of course, officially, there is much tut-tutting and hand-wringing over Ukip’s success in Scotland. We’re all supposed to be simply appalled that these fruitcakes have won a seat in the European parliament. Terrible stuff.

Come off it. These are the lamentations of a crocodile. Secretly – and sometimes not so secretly – Unionists are delighted by Farage’s success in Scotland. He was supposed to be Alex Salmond’s useful nutter; instead he has become the Union’s secret weapon.
