Ex-WA premier faces insider trading trial Former West Australian premier Brian Burke has pleaded not guilty to four charges related to insider trading. Burke, 66, entered the plea in person at Stirling Gardens Magistrates Court in Perth on Wednesday. His co-accused, former Patersons Securities stockbroker David John Massey, 57, also pleaded not guilty to the same charges. The charges followed secret recordings by the Corruption and Crime Commission (CCC) of Burke's phone calls some six years ago, which were passed on to federal authorities. It is alleged the charges relate to shares in Australian Securities Exchange-listed telecommunication company Amcom. The pair are next scheduled to appear in court on July 22.
