May called last year's general election in hopes of strengthening her hand ahead of all-important Brexit negotiations.
Monday's cabinet reshuffle tore back the curtains, revealing the prime minister's diminished authority in the cold, unforgiving light of a January morning.
Worse than that, alongside the prime minister's willingness to move the health, education and business secretaries, a flurry of tweaks to other cabinet posts - shifting David Lidington from justice to replace Green; moving David Gauke in turn from DWP, where he had been for just seven months, into justice - suggested far from prioritising complex domestic reforms, such as the rollout of universal credit, May was unwilling to let anyone stay in post long enough to complete the tough task she had allotted them.
The government crisis was sung since forced resignation in December of its number two, Damian Green, who lied about finding in 2008 of pornographic material on his work computer.
The reshuffle took on a freaky twist Monday morning as the official Conservative party Twitter account tweeted an image congratulating Secretary of State for Transport Chris Grayling on becoming the chairman of the Conservative party.
But the day began in a farcical fashion when her Conservative party announced a new chairperson on Twitter, only to delete the tweet and later name another lawmaker for the post.
Scottish First Minister Nicola Sturgeon, who favours the United Kingdom remaining in the single market and customs union, said Mr Davis's words were "extraordinary" given the government had set aside £3.7bn to prepare the United Kingdom for the possibility of leaving without an agreement.
"No wonder Theresa May's struggling to negotiate Brexit - she can't even organise a reshuffle", tweeted opposition Labour MP Stephen Kinnock.
After months of reshuffle speculation, when the time came, Theresa May's ministers couldn't be budged - not the ones that truly matter at least.
The reorganization will extend through Tuesday, when there could be a clutch of new mid-ranking ministers, commentators said.
In a letter to Mrs May last month, extracts of which have been seen by the Financial Times, he warned it was potentially discriminatory of European Union agencies to have issued guidance to businesses stating that the United Kingdom would become a "third country" outside the European Union without any reference to a future trade deal sought by both sides.
Johnson, a leading Brexit supporter, kept his job at the foreign office, despite challenging May's strategy in 2017, as did fellow eurosceptic Liam Fox, the global trade minister.
Her move was quickly followed by a bigger job for Margot James, made minister of state in the department for digital, culture, media and sport, and for Harriett Baldwin, who became a minister of state at the Foreign Office.
"Clearly, she's keen to put her stamp on the party and do the things you try to do with reshuffles - bring through new talent, make the party more representative - but she's very constrained", Rob Ford, a professor of political science at the University of Manchester, said of May's decisions.
