The 72-year-old Scottish broadcaster explained on social media that he "couldn't be happier" to sever ties with the newest news outlet in the UK. He wrote on Twitter: "After weeks of talks with @GBNEWS, resulting in exit settlement, the channel then broke it by briefing Mail on Sunday with load of smears/lies then unilaterally cancelling exit deal.

       "Leaving me free to do, say whatever I want + never again be on GBNews.

       "Couldn’t be happier."

       Last night's tweet also sparked much reaction on social media, including from fellow journalists and an employee at GB News.

       Lucy Jones, a senior producer at GB News, responded indirectly by saying: "Let’s remember GB News is more than just one presenter.

       "We’re a dedicated team working tirelessly to provide a channel that stands for free speech & fair debate.

       "Those who watch will see that.

       "I count myself lucky to learn and work alongside some brilliant people."

       But not everyone on social media sprung to the defence of GB News.

       Adrian Hilton, a conservative academic who has contributed to several national publications, retweeted Neil's tweet challenging GB News' chief executive office.

       "Isn't this just so unutterably shoddy of Angelos Frangopoulos," he said.

       "When you make an agreement, you honour it.

       "If you unilaterally cancel it and breach confidences, why should anyone ever again trust anything you do or say?"

       And the BBC North American editor Jon Sopel has even warned this might not be the end of it.

       Mr Sopel, who worked alongside Neil during the Scotsman's last time hosting a BBC programme, when covering the 2020 US Presidential Election, claimed: "Something tells me this isn't the last we've heard about this..."

       Mr Neil's comments have come just a week after he announced he had resigned from his position as GB News' chairman and as the channel's flagship presenter.

       Following his resignation, Neil then appeared on the BBC's Question Time programme in Croydon.

       During his return to the UK's national broadcaster, the veteran journalist said he was in a "minority of one" among senior management.

       Neil also told viewers to "draw your own conclusions about why I'm here and now with GB News" after he was asked whether the channel had become the British version of Fox News.

       He went on to explain: “More and more differences emerged between myself and the other senior managers and the board of GB News.

       “Rather than these differences narrowing they got wider and wider."
