MP Andrew Broad of the Nationals will not contest the western VIC seat of Mallee in the next election following revelations of his use of a sugar daddy website to meet women overseas while he was on government business.

"Today I have informed the president of the Victorian Division of The Nationals that I am withdrawing my nomination to contest the Division of Mallee at the next federal election," Mr. Broad said in a statement.  "After recent media stories about my private life, it is clear that the people of Mallee will be best served in the next parliament by a different Nationals candidate."

Andrew Broad already resigned his role as an assistant minister yesterday.  A replacement will be preselected early next year.

Before his statement came out, Broad met with Deputy Prime Minister and Nationals leader Michael McCormack about his future in parliament, which it turned out is "none".  Mr. McCormack said that Broad will have to reimburse Australian taxpayers for any public money that was used in his meeting or meetings with women on government time. 

Broad's rapid decline doesn't necessarily solve a problem for McCormack, however.  From his statements on Tuesday, it seemed apparent that McCormack knew about at least some of the allegations against Broad for a few weeks.  But he didn't tell PM Scott Morrison until after they were reported by New Idea magazine.

"I don't tell the prime minister everything about every member of parliament," said McCormack, "He's got enough on his mind at the moment and quite frankly I thought it was a matter for Andrew to sort out with his family.

"All I was aware of was that he was on a personal trip, that he'd sought a date," he added.  "He'd gone on that date and, he told me, that nothing further had occurred, apart from the fact that, later on, the person with whom he went on the trip, had allegedly made contact with him and as a result of that contact, then he was concerned - and I said, 'Well, if you're concerned, and if you haven't done so already, you should go to the proper authorities', and he obviously has."
