Crossbench senators, including Jacqui Lambie, seek secret union report

Crossbench senators are seeking access to a confidential volume of the report of the royal commission into union corruption.

Two volumes of the interim report of the royal commission headed by Justice Dyson Heydon were publicly released in December but one volume was kept secret because it deals with threats to witnesses. Department of Prime Minister and Cabinet officials on Tuesday confirmed the confidential report had been received, but would not say how many people had read it or how many agencies had access to it.
