Labour Party politics have always been by turns ferocious and genuinely fraternal, bitter and yet sentimental. They have their little rituals, and they have their own little hypocrisies. Anyone who has ever contemplated pushing their best friend under a bus in order to get his or her job will be familiar with the fine-sounding euphemisms that are used to disguise ruthless ambition.If you want to understand what it’s like inside the belly of the beast, I strongly recommend a trip to the White Bear in Kennington this week to see Triggered.
