Fox News has confirmed that Maria Bartiromo has left both Fox News and Fox Business Network with immediate effect, after 12 and a half years at the broadcaster. New details have emerged since the initial announcement: Fox has given no reason for her departure, but a review of her programmes shows she had not appeared on Fox's channels since early August, suggesting the split predates Thursday's statement. The abrupt nature of her exit recalls Fox's earlier sudden removal of primetime host Tucker Carlson, and is notable given the network's usually stable on-air lineup and its leading position in US television news ratings.

Beyond the previously reported changes to her FBN shows, it has now emerged that Fox News Channel's Sunday Morning Futures will be hosted by Jason Chaffetz this Sunday, with a permanent replacement still to be named. The article also fills in Bartiromo's background: she rose to prominence at CNBC, anchoring On the Money and Closing Bell, before joining Fox in 2013, where she became a fixture of FBN and co-hosted a 2016 presidential debate. She is known for her close ties to President Trump, a frequent guest on her programme whom she interviewed only a few months ago.
