Context. The highest redshift quasars at z 6 receive considerable attention since they provide strong constraints on the growth of the earliest supermassive black holes. They also probe the epoch of reionisation and serve as “lighthouses” to illuminate the space between them and the observer. The source J1427+3312 () has recently been identified as the first and so far the only known radio-loud quasar at .
