Popular New South Wales Independent MP Rob Oakeshott has announced he will contest the federal seat of Lyne, now held by the Nationals.
Mr Oakeshott is the state MP for Port Macquarie, which lies within the federal electorate.
A by-election for Lyne is necessary after the retirement of former deputy prime minister and Nationals leader Mark Vaile.
The Nationals have named former Port Macquarie mayor Rob Drew as their candidate for the seat.
