At last, and two years too late, May has chose to assert her authority over her colleagues when it comes to controlling the process that will lead the United Kingdom out of the European Union.
The Gibraltar Government has vowed to leave "no stone unturned" to protect the Rock ahead of its departure from the European Union as the UK Government was thrown into turmoil by the sensational resignations in quick succession of Brexit Secretary David Davis and Foreign Secretary Boris Johnson. Both are hard Brexiteers of high political ambition.
May met with Conservative lawmakers in a packed room at Parliament, in a bid to calm the feverish atmosphere in the deeply divided party.
Opposition Labour leader Jeremy Corbyn said the Cabinet ministers had "jumped the sinking ship".
"He said it here in Dublin a year ago, that he didn't want a Norway type agreement because he felt that Britain would be rule takers - and that's the fundamental difficulty, Brexiteers are failing to grasp that when you enter an agreement with 27 other countries you agree to share a sovereignty".
She said: "I'm looking forward to seeing President Trump not only at the North Atlantic Treaty Organisation summit coming up in the next couple of days but also obviously when he comes to the United Kingdom at the end of the week".
The carefully choreographed meeting last week resulted in a deal May believed her cabinet had signed up to, which would create a "UK-EU free trade area" for goods, governed by a "common rule book". Hardcore Brexiteers, not surprisingly, suspect that, even before serious negotiations with Brussels have commenced, the British government is making concessions that go against their interpretation of what the British people voted for in June 2016.
Mr Rees-Mogg said: "Unfortunately Chequers was a breakdown in trust".
The government has battled to find a way of tackling these while maintaining access to European Union markets and avoiding burdensome customs arrangements that could damage businesses, with some leading companies warning they could cut investment or withdraw from Britain in the wake of a no-deal Brexit.
She needed a decisive majority to ensure that a Brexit compromise would carry in spite of the Remain and Leave extremes in her parliamentary party. The truth is that Brexit has always been more about the internal politics of the Tory party than it has been about the national interest. "Party or country, career or principle?" "The EU is massively responsible". It came in a week in which Jaguar Land Rover expressed its concern that a hard Brexit would be a source of grave concern for the company, which might force it to reconsider an £80 billion investment in its production plants in the United Kingdom, and consequently put 40,000 jobs at risk.
Brexit negotiations with Brussels are also expected to resume next Monday.
May leaned with some success on most of her Cabinet colleagues.
But Davis's resignation, followed by his number two at the Department for Exiting the EU, Steve Baker, shattered that truce and put pressure on Johnson to follow suit.
Mrs Rudd's public slapdown came after Mr Johnson, who is widely regarded to have ambitions to become prime minister, penned a lengthy article for the Daily Telegraph that laid out his Brexit blueprint.
