Sharon Grierson, the Labor member for Newcastle in the House of Representatives, has announced that she will not contest the next election.
The former teacher and school principal has held the New South Wales electorate for four elections since 2001.
She is the second Labor member of the House to reveal retirement plans ahead of an election the ALP is expected to lose in a landslide. Steve Gibbons, the member for Bendigo since 1998, announced his departure in August last year.
Grierson polled 47.89% of the primary vote in 2010. After preferences, she was elected with 62.49% of the two-party-preferred vote, a swing against her of 3.42% from the 2007 election.
Newcastle has been held exclusively by the ALP since 1901. Grierson is only the fifth member to hold the seat.
Grierson made a video statement on her retirement:
