Broadcaster Eamonn Holmes is in hospital after having a stroke, GB News has said.
The channel said Holmes was "taken ill last week" and it was "later confirmed he had suffered a stroke".
He is "responding well to treatment", a statement said, adding that Holmes's "colleagues and everyone at GB News wish him a speedy recovery".
Holmes, 66, has a TV career spanning decades. He presented programmes on Sky News and ITV, before joining GB News in 2022 to front its breakfast show, which he co-hosts with Ellie Costello.
Fellow GB News presenter Alex Armstrong is due to stand in for Holmes in the coming week, the channel reports.
CEO Angelos Frangopoulos described Holmes as a "loved member of the GB News family".
The former This Morning host has previously spoken about various health issues, including spinal surgery, a double hip replacement, and his struggles walking and using a mobility scooter.
Holmes, originally from Northern Ireland, has held a number of broadcasting roles throughout his career.
He was a presenter on UTV's Good Evening Ulster, later moving to GMTV for its first broadcast in January 1993. He remained there until 2005.
Holmes also presented Sky News's breakfast programme Sunrise and, more recently, co-hosted ITV's This Morning with Ruth Langsford who he married in 2010.
In 2024, a spokesperson said the pair had "confirmed their marriage is over and they are in the process of divorcing".
He was made an OBE for services to broadcasting in the 2018 New Year's Honours List.
A stroke occurs when blood stops flowing to part of the brain, according to NHS guidance.
Possible symptoms include face weakness, where one side of the face might droop, arm weakness and speech problems.
Urgent medical intervention is needed if a stroke is suspected.
