Newton is being backed to take over the show full-time following his success on This Morning since 2009, according to Broadcast.
His time on This Morning has included the launch of special weekend editions and an extension of the show's summer run.
Newton will be working with ITVS daytime and lifestyle creative director Fiona Keenaghan, offering his advice to the rest of the Daybreak team.
It is believed that he has a "populist touch", which can revive the breakfast show's fortunes.
Daybreak has underperformed in the ratings and has failed to match its predecessor GMTV since its launch.
Adrian Chiles has had his role reduced as a presenter, while editor Ian Rumsey announced his departure last month.
