Islington is a bellwether, and also a joke: the most unequal borough in London, where social housing leans against £4 million terraces (for now, loyal Conservative voters, only for now), and also the holy font of Blairism as it appears in ‘It’s Grim Up North London’. Here, it is said, they sang the Blairite version of the Red Flag: ‘The People’s flag is deepest pink/ It’s not as red as people think/ So raise the scarlet banner high/ The college song, the old school tie.’
