Tony Abbott to be named new Liberal Party president

"He'll be elected unopposed," the official said, referring to Mr Abbott, who served as coalition prime minister from 2013 to 2015.

Former foreign minister Alexander Downer has been nominated for vice president of the party - one of five nominees for four second-in-command positions, the official said.

Mr Downer will contest for the vice president role after withdrawing from a race with Mr Abbot for the top job in the party's organisational wing, local media reported.

The new role will mark a return to the political stage for Mr Abbott after he lost his Sydney seat of Warringah at the 2019 federal election.
