Labor claims seat of Mt Lawley for first time, also wins Mirrabooka and West Swan

Mr Millman took the seat from Liberal Speaker of the House Michael Sutherland with a swing of almost 13 per cent.

“What we have seen is a statewide swing to Labor which is a testament to the energy and enthusiasm of our campaign and the merit of our policies,” he said.

In a close race, Mr Sutherland had received 7180 primary votes as of this morning and Mr Millman 7145, with the pair sitting at 46.24 per cent and 53.76 per cent two party preferred, respectively.

Mr Sutherland said early on election evening that the One Nation deal had been “out of our hands” and “one of those things I had to deal with”.

He was not involved in the preference deal, and there was no One Nation candidate in Mt Lawley, but he conceded that some constituents had been unimpressed with the arrangement.

Mirrabooka MLA Janine Freeman retained her seat against Liberal candidate Lily Chen in a landslide win.

Ms Freeman has so far received 9793 primary votes, with 69.25 two party preferred, and Ms Chen 4,118 votes and 30.75 per cent two party preferred.

West Swan MLA Rita Saffioti also dominated the election count and has so far received 59.6 per cent of the primary vote, compared to Liberal candidate Rod Henderson’s 25.15 per cent.

The Labor transport spokeswoman is tipped to become a minister in the new government.
