Police Minister Liza Harvey set to become deputy Premier in WA's new-look Cabinet Police Minister Liza Harvey is tipped to become deputy Premier. POLICE Minister Liza Harvey is set to become WA's deputy premier in a major pre-election reshuffle of a new-look Cabinet before the 2017 election. Informed sources told The Sunday Times yesterday that Ms Harvey had the support of her Liberal colleagues to replace Dr Kim Hames, who is retiring at the next election. That move would bump off Transport Minister Dean ­Nalder, who had been widely tipped to become Colin ­Barnett's second in command. But the elevation of Ms Harvey as deputy leader did not necessarily mean she would become leader when the Premier eventually retired. Sources said Mr Nalder wasn't ready for the responsibility of the role yet and needed more time to prove himself as a minister, "let alone become deputy leader." Meanwhile, National Party MP Colin Holt is likely to be one of three new ministers in Mr Barnett's rejigged team of ministers as part of an exodus of current Cabinet members. Sources said Mr Holt - the leader of the Nationals in the Legislative Council - was likely to replace National Party MP Terry Waldron, who is expected to announce his retirement before the next poll. His sport and recreation portfolio will go to a Liberal. Party sources said Mr Barnett wanted a Liberal, rather than a National, to oversee the development of the $1.2 billion sports stadium at Burswood. Mental Health Minister Helen Morton is also said to be planning retirement at the next election, while Planning Minister John Day is considering his future in politics. Former environment minister Donna Faragher, who quit as a minister to start a family, is tipped to replace Ms Morton. It is understood Lower House Liberal MPs Sean L'Estrange and Andrew Mitchell are front runners to fill Dr Hames" seat in Cabinet. Rejuvenating his Cabinet will be an important factor in Mr Barnett's quest to win a third term of government. He recently announced he intended to contest the election, which is due to be held in March 2017. WA political analyst Dr Harry Phillips said yesterday Mr Barnett had sent a "clear signal that he is confident of a third-term victory." Originally published as Harvey pips rival at deputy's post
