John Noseworthy, the Newfoundland and Labrador auditor general who blew the whistle on a legislative spending scandal that sent a string politicians to jail, is retiring from his office.

Noseworthy, who is in the ninth year of a 10-year term, confirmed to CBC News that he is retiring as auditor general, as of July 31. His term was to run through August 2012.

Noseworthy told CBC News he is leaving his position early to seek other professional opportunities, although he would not elaborate.

Asked if he was considering a political career, Noseworthy said, "[I am] not going to rule out any opportunity that may come to me."

Noseworthy released the first of a series of explosive reports in June 2006 that documented what was proved to be a massive fraud involving several members of the house of assembly.

Noseworthy's reports led to jail sentences for former Tory Natural Resources minister Ed Byrne - who had been the government house leader when the scandal forced him to resign from cabinet - as well as Liberals Jim Walsh and Wally Andersen and New Democrat Randy Collins.

Also imprisoned were Bill Murray, the disgraced financial director of the house of assembly, and businessman John Hand, whose companies defrauded taxpayers.
