The crowding of the centre-right is having profound consequences for Australian politics, not just Turnbull’s troubled time as prime minister.
Ahead of Saturday's crucial byelections, senior Labor Party figures have described a vote for Pauline Hanson's One Nation party as a vote for the Coalition. What do the records show?
On Saturday, five federal seats will have a byelection, with particular attention being paid to tight races in Longman and Braddon. And all have implications for the major parties and their leaders.

Clive Palmer believes he can recapture the magic that saw him elected to Parliament in 2013, but what his new party – and others on the right – need is more discipline.

The seemingly disproportionate media attention given to One Nation is the result of a potent news-making brew.

Voters in Queensland and the rest of Australia may need to accustom themselves to a new norm of tight, drawn-out contests, where party leaders’ election night speeches might be obsolete.
