New England MP Barnaby Joyce sworn in as Deputy Prime Minister after Nationals leadership spill

It is the third time Mr Joyce has held the role. He previously resigned from the position in the wake of sexual harassment claims and was also removed due to eligibility criteria relating to his New Zealand citizenship - which he has since renounced.

On top of being Nationals leader and Deputy Prime Minister, he has also taken on the job of Minister for Infrastructure and Regional Development.

The swearing-in ceremony was quite unique with Prime Minister Scott Morrison attending via Zoom from The Lodge as he continues quarantining after returning from the UK.

Mr Joyce's partner, Vikki Campion, as well as their two young sons, Sebastian and Thomas, were also at Government House, seemingly on photo-bombing duties, to see their father sworn in by Governor-General David Hurley.

There is likely to be a cabinet reshuffle in the coming days, with former minister Bridget McKenzie expected to make a return to the frontbench.

David Littleproud will continue in his role of Deputy Leader of the Nationals, which he was promoted to under Michael McCormack.

Mr Joyce's stance on climate change is expected to come under the microscope even more now he is in the new role, with his popularity among regional women also being questioned in the wake of his last resignation.

Mr Joyce was approached for comment but did not respond.
