(abridged) Relativistic jets, formed in the vicinity of central supermassive black holes in AGN, show ample evidence connecting them to physical conditions in the accretion disc and broad-line region. The jets are responsible for a large fraction of non-thermal continuum emission (particularly during powerful flares), which makes understanding their physics an important aspect of studies of blazars characterised by profound flaring activity arising from extremely compact regions. Imaging and polarimetry of radio emission on milliarcsecond scales provided by very long baseline interferometry (VLBI) offers a range of possibilities for studying ultra-compact regions in relativistic jets and relating them to main manifestations of the blazar activity in AGN. Simultaneous monitoring of optical/high energy variability and evolution of parsec-scale radio structures yields arguably the most detailed picture of the relation between acceleration and propagation of relativistic flows and non-thermal continuum generation in blazars. These effects are reviewed and discussed in the context of deriving accurate and self-consistent models for central regions of blazars.
