Liam Fox has become the latest Cabinet minister to publicly back Boris Johnson's call for more spending on the NHS after Brexit.
The Foreign Secretary was rebuked by Theresa May for making his demand for an extra £100 million a week for the NHS public knowledge before a Cabinet discussion on health yesterday (January 23).
But his position, that money recouped as part of a "Brexit dividend" when Britain stops sending large sums to Brussels should be spent on the NHS, was publicly backed by Health Secretary Jeremy Hunt and now the International Trade Secretary.
Their interventions could increase pressure on the Prime Minister to commit to boosting health spending after Brexit.
Fox told the BBC: "I think there is a case to spend more money on healthcare and we're spending more money on healthcare.
"Exactly how we spend the dividend that comes from leaving the European Union will be determined by the priorities we face at the time.
"I find it absolutely unthinkable that health would not be amongst the top of those."
May had pre-empted Johnson as ministers gathered at No 10, telling the meeting any "Brexit dividend" would be allocated according to the Government's priorities, including schools and housing, as well as health.
She also warned ministers they should keep Cabinet discussions private.
Some Tory MPs were angered by the situation, with former minister Anna Soubry warning the Prime Minister that Johnson would destroy her Government unless she sacked him.
She claimed he has shown "longstanding incompetence and disloyalty" and unless May acts now "Boris will bring her down."
