Nationals deputy leader Barnaby Joyce has warned Liberal MPs the coalition agreement will need to be renegotiated if Malcolm Turnbull wins a challenge against Tony Abbott.

There is no love lost between the junior coalition partner and Mr Turnbull, going back to his time as opposition leader.

"The one thing they need to realise is they will have to renegotiate the coalition agreement," Mr Joyce told AAP.
