WA deputy premier coy on cabinet reshuffle

Western Australia's deputy premier has refused to give away any hints about the cabinet reshuffle to be announced this week, but says she is happy with her current responsibilities.

Liza Harvey, who is the minister for police, road safety, training and workforce development and women's interests, said she would take on whatever roles the premier wanted her to have.

"I have always said if the premier wants me to take something else on I will do it if he thinks it's better for the state," she told 6PR radio on Monday.

Premier Colin Barnett has flagged significant changes to his cabinet that will go to the March 2017 election, with some senior members potentially facing the chop.
