(For the actual police division, see Special Branch.) Special Branch is a British television series made by Thames Television for ITV and shown between 1969 and 1974. A police drama series, the action was centred on members of the Special Branch anti-espionage and anti-terrorist department of the London Metropolitan Police. The theme music for series one was by Norman Kay. For series two, three and four it was by Robert Earley. Like the later The Sweeney, the on-screen offices of Special Branch were located in Hammersmith.
