It’s a universal truth that all political parties are coalitions. The Labour Party, for example, is a coalition of old Labour traditional socialists to modernist “Blairite” factions and everything in between. The Conservatives have (a declining faction of) one-nation-type Tories, ideological Thatcherites, and further right almost-nationalist types.
The Liberal Democrats are still broadly divisible into the Liberals and the SDP, with a mix of those who joined when they were a left-of-Labour party, and have since pretty much melted away. And the Greens are an alliance between the middle-class, tree-hugging liberals of old, and old socialist elements floating around since Kinnock declared war on Militant Tendency.
But UKIP — UKIP have perfect the mongrel art of the political party. Farage is a sometime-Thatcherite, with a taste for the little Englander world-view, whilst UKIP’s first, and at time of print sole, MP is more of a classic liberal. And in elections in the north of England, they have been manoeuvring to be an Old Labour replacement.
So with such a varied composition, it can be no surprise that there are ideological fault-lines all over UKIP’s topography. And they seem to be coming to a particular head in South Essex.
