Can there be a left UKIP? Taking this metaphor perhaps a bit more literally than intended, the only way I can see it translate is in terms of the left-Nationalist Jose Marti tradition in Latin America, with the US replacing the EU as the bete noire, perhaps an appeal to certain military officers up to say the level of colonel, and a tenderness for, um, charismatic leadership. Arguably, George Galloway has taken this about as far as it can go here.
Actually, I'm not sure that there is a left of labour space so much as a kind of weary resignation that Labour has become an entirely technocratic party behind which people glumly trudge along behind holding up banners saying 'squeezed middle' and 'hardworking families'. If the Kippers are a kind of revolt of the rightwing imaginary, a performance rather than a party, Labour seems intent on maintaining a complete lockdown on anything that might generate ungovernable enthusiasm. Seems to be wiorking so far, more or less.
