Succession star Brian Cox has joked that he finds it easy to comply when fans ask him to tell them to "f*** off".

The actor, 76, stars as media conglomerate CEO Logan Roy in the hit TV series and is well known for the sweary catchphrase.

During an appearance on This Morning, he admitted that he has become more "potty-mouthed" since he was cast in the role of the mogul four years ago.

Cox also told the show's hosts Holly Willoughby and Phillip Schofield that plenty of people ask him to curse when they meet him.

"Human beings are really weird, they really are weird - 'Can you please tell me to…', you know," he said, as the presenters laughed.

"And you are going, 'Happily!'"

"That’s why it’s the easiest thing to say because you are quite happy to tell them to you know what!" he chuckled.

Schofield admitted that he wouldn't mind having Cox say it on his Instagram.

And after This Morning had wrapped for the day he shared a video of him and the actor, who was turning the air blue.

The pair were standing together on the set of the ITV show as Cox said: "So I have been trying to tell this man for such a long time to just f*** the f*** off."

"And he simply will not f*** off," he added, as Schofield started to laugh.

"Love this man," wrote the presenter.
