%X Very long baseline interferometry &#40;VLBI&#41; polarisation measurements provide information about the parsec-scale magnetic field structures in compact active galactic nuclei &#40;AGN&#41;, as well as the densities of relativistic and thermal electrons in the radio emitting regions. This paper reviews the role of polarisation VLBI in studies of AGN variability on both relatively long and short &#40;intraday&#41; timescales.
