Supplementary information

The file contains Supplementary Discussion, supplementary Methods and additional references. The Supplementary Discussion presents calculations that relate the rate of rotation of the optical polarisation vector and apparent speed of the knot of emission to the angular velocity of the knot. This leads to an estimate of the speed of rotation and distance from the black hole of the footpoint of the jet's magnetic field in either the accretion disk or the ergosphere. The Supplementary Methods give details of the observations and data analysis are given.
