Good Morning Britain staff allegedly threatened to stop working when they heard Piers Morgan was in talks to return to the ITV show as a guest.
The former co-host was reportedly set for a comeback to promote his new talk show, Piers Morgan Uncensored, which launched earlier this week on Rupert Murdoch's TalkTV Channel.
Morgan's appearance would have happened a year after he stormed out live on air following a spat with weather presenter Alex Beresford, 41, over remarks he made about Meghan Markle following her tell-all interview with Oprah Winfrey.
