Labor's great WA exodus

Senate - March 1

* Reason for leaving: Labor's stance on mariage equality

"How can I, in good conscience, recommend to people that they vote for a party which has determined to deny its parliamentarians a conscience vote on the homosexual marriage question?"

Gary Gray, 57 - House of Representatives - February 16

* Reason for leaving: To support the renewal of the Labor Party

"I think we'll lose (the next election), but it's not about being able to bear the strain of that."

Alannah MacTiernan, 62 - House of Representatives - February 12

* Reason for leaving: Impatience with the progression of her federal career

"I believe it is more sensible for me to pass on the baton to someone who can build a bigger role over the next decade."

Melissa Parke, 49 - House of Representatives - January 22

* Reason for leaving: To be closer to family and travel less
