Nicola Sturgeon has said that having Boris Johnson as Foreign Secretary is bad for the UK's reputation, branding him "embarrassing".
A source, claiming to be a supporter of Johnson, said that moving him would go down "like a bucket of cold sick" with those who'd voted for Brexit. "There's a stench of death emanating from Downing Street".
British Prime Minister Theresa May signalled in an interview that she might demote foreign secretary Boris Johnson, a Sunday newspaper said, after she faced an open rebellion from within her party this week.
Tory MP Nadine Dorries was more direct, telling ITV's Peston on Sunday: "If I were Prime Minister the person I would be demoting or sacking would be Philip Hammond". I do not know if they are really my friends and allies or if they represent some sinister band of imposters.
"I heartily disagree with the sense, tone and spirit of what they are quoted as saying".
She denied she cried after the "cringe-worthy" conference speech and hit out at some of the media portrayals of her: "One minute journalists are accusing me of being an ice maiden or a robot, then they claim I'm a weeping woman in dire need of a good night's sleep..."
Asked what she might do with him, Mrs May replied: "It has never been my style to hide from a challenge and I'm not going to start now". Johnson, seen as a potential successor to May, said that Conservative lawmakers pushing to unseat her were "nutters", adding that a change would lead to demands for another election that could bring a resurgent Labour party back to power.
A cabinet minister told the Telegraph that Hammond "has completely failed", is "miserable" and "is making Brexit hard".
Brexit-backing Tory MPs have called on Mrs May to move Mr Hammond away from the Treasury because they think he is too gloomy about Brexit.
But defence secretary Sir Michael Fallon insisted there were no divisions within the cabinet.
Johnson's clarification has being backed by Crispin Blunt, who told Sky News today that the foreign secretary had supported May in his conference speech and now in the WhatsApp message: "He's declaring his loyalty, as he did in his speech, and he's declaring it privately".
But Theresa May's official spokesman did not rule out a reshuffle. The reshuffle, according to the Sunday Times, would take place after an October 19-20 summit in Brussels where May will be hoping for a breakthrough few think possible.
"We've got a Prime Minister who's not up to it. Boris Johnson, who's an absolute disgrace to this country, we've got a Cabinet at war and a Conservative Party deeply divided".
