ONE of the Labor Party's most senior respected figures, Senator John Faulkner, has announced he will retire at the next Federal Election.
The New South Wales federal politician has been a stalwart of the party since 1989, and a key leader of federal Labor's left-wing.
A statement from Sen Faulkner thanked the party for the unqualified honour of representing it in parliament, and called for more action on internal corruption.
Sen Faulkner, a long-time advocate of cleaning up electoral rules, political donations regulations and transparent government, will serve out his current term until July 2017.
A statement from Labor leader Bill Shorten thanked him for his service, and said he had a proud legacy as a "formidable and forensic Senator".
"He has never cut the cloth of what he says to suit the fashion of the day," Mr Shorten said.
"John is a keeper of the Labor flame. All of us in the Labor Party thank him for the service and guidance he has given our party, and our country."
