Long-standing Labor MP Anthony Byrne will resign from federal politics at the upcoming election.

Mr Byrne, who has held the Melbourne-based seat of Holt since 1999, won’t contest the May election after growing pressure to quit politics.

The veteran MP was a whistleblower on branch stacking allegations involving disgraced Victorian state MP Adem Somyurek.

During a corruption inquiry in Victoria last year, Mr Byrne admitted to engaging in branch stacking and used taxpayer-funded parliamentary staff to create fake branch members.

The revelations led to him stepping down from his role on a powerful parliamentary committee, but resisted calls to step away from federal politics.

Mr Byrne wrote to the ALP’s national secretary on Thursday advising he would not be a candidate at the upcoming election.

Labor’s national executive will oversee the selection process for candidates, due to it currently overseeing the Victorian branch of the party.
