Noreen Hay has been sacked from her role as NSW parliamentary secretary following allegations of involvement in former police minister Matt Brown’s drunken post-budget romp.

Mr Brown resigned from his newly appointed role as police minister yesterday when The Australian uncovered his inappropriate behaviour at a party held in Parliament House three months ago, where he stripped down to his underwear and allegedly straddelled Ms Hay’s chest.

Mr Brown admitted to dancing in his underwear but denied the second incident. The Wollongong MP also denied claims that Mr Brown simulated a sex act with her.

Premier Nathan Rees told local media that there was no link between Ms Hay’s dismissal and Mr Brown’s inappropriate conduct.

"Historically parliamentary secretaries have come some time … the announcement of them has come some time after the Cabinet itself," Mr Rees said on ABC radio.

"There is simply only so many things you can consider in any given day and that’s the reason for that."
