Coalition backbenchers are preparing for a showdown on net zero as pressure mounts on Sussan Ley's opposition to resolve its position, with speculation more MPs could join Barnaby Joyce in quitting if the policy isn't dumped.

Liberal and Nationals MPs have been invited to remain in Canberra after the upcoming sitting week for a three-hour, closed-door debate on energy policy, including net zero by 2050.
