Federal Labor MP Gary Gray has announced he will not recontest the next federal election.

The former resources minister and special minister of state in the Rudd government was first elected to the seat of Brand in 2007.

He has followed fellow West Australian MPs Alannah MacTiernan and Melissa Parke, who have also announced they will not be contesting their seats at the next poll.

Labor hold the electorate of Brand, in Perth’s southern suburbs, by 2.9 per cent but becomes marginally safer for the ALP following a redistribution of WA seats.

Mr Gray survived a preselection challenge from rivals within the party late last year.
