Peter van Onselen, who has been the political editor of Channel Ten for four years, is reportedly leaving the network.
He will reportedly be returning to academia.
His departure leaves the struggling network with a new vacancy.
He joined the network in 2018 after working at Sky News Australia. It is believed that he will continue his regular column in The Australian.
His first journalistic achievement was a biography he wrote with Wayne Errington, which contained explosive comments about John Howard’s former treasurer Peter Costello.
The success of his book helped van Onselen land a regular column in The Australian and a variety of television hosting gigs.
Channel Ten has not announced the future of its political coverage.
On Twitter, he noted the difficulties of the daily commute between Canberra and Sydney.
In his farewell message, van Onselen thanked the staff members of Channel Ten for their hard work.
