Hoot - fyi, Clerkenwell is now an area of central London in the London borough of Islington - the council's website says:

"Prior to 1900, local government responsibilities for the area were administered by Islington, Clerkenwell and St Luke's parish vestries. In 1900, these were replaced by the two, newly formed metropolitan boroughs of Finsbury (Clerkenwell and St Luke) and Islington. These merged to form the present borough in 1965, as part of a London-wide reorganisation of local authorities."
