The Liberal Party has maintained a tight lead ahead of Labor in a key NSW seat. 

In the closest race, Liberal candidate Andrew Constance is 286 votes ahead of sitting Labor MP Fiona Phillips in the electorate of Gilmore. 

But in a loss for the party, Julian Simmonds became the latest Liberal MP to concede defeat following the federal election on Saturday. 

Greens candidate Elizabeth Watson-Brown is expected to win his Brisbane seat of Ryan. 

In the electorate of Brisbane, Labor’s Madonna Jarrett is holding on to her primary-vote lead over the Greens, placing her in a strong position to take the seat from Liberal MP Trevor Evans.

She is 672 votes ahead of Greens candidate Stephen Bates. 

As of Thursday afternoon, the Australian Electoral Commission has Labor with 75 seats to the coalition’s 60, the Greens with three seats, 12 on the cross bench, and the seat of Macnamara without a preference count.

The Greens are hoping to secure three seats in the lower house by winning electorates previously held by the two major parties. 

Leader Adam Bandt said his party will not yet be conceding or declaring victory in the seats of Brisbane and Macnamara in Melbourne, where the margins are slim. 

The Liberal Party will examine where its campaign went wrong following the heavy election loss. 

The review, announced on Thursday, will be overseen by Senator Jane Hume and the party’s former federal director Brian Loughnane.

The review comes as Liberal MPs meet on Monday to elect a new leader, with Peter Dutton tipped for the job.

The campaign review will focus on the “long-term challenge” for the party presented by independents, after many seats were lost to so-called “teal” candidates.
