Now coincidence of coincidences, just as Mr Raab arrives in town, the European Commission will publish a paper instructing EU governments to do more to prepare for the possibility of a no-deal Brexit which - it warns - would have a considerable impact on European businesses and citizens.
Labour MP Alex Sobel, a supporter of the Best for Britain campaign for a second referendum, said: "Barnier today has politely ripped apart the embattled prime minister's plan only hours after she insisted there would be no further compromise on her side". Britons should be "great independent actors" on the world stage, not "rule takers", he said.
"It is not too late to save Brexit", Johnson said in his speech.
The Times says it understands that Mrs Leadsom is concerned about the accuracy of the minutes taken by officials at the Chequers summit and may request changes to them.
"We must try now because we will not get a chance again".
However, he admitted that "we need to check if the proposals laid out in the White Paper are compatible with the principles set out in March by the EU's 27 leaders".
He said he would ask the British government whether the blueprint met European Union guidelines, including on the movement of goods, capital, people and technology. It's also the "only way" to secure frictionless trade with the bloc - something "every Conservative should support", he said.
Dr Fox, who backed the Chequers plan despite the resignations of fellow Brexiteers David Davis and Boris Johnson, insisted it gave the United Kingdom freedom to strike trade deals despite the proposal for aligning with Brussels' rules on goods.
But he questioned the UK's plans for a common rulebook as it only referred to goods checked at the border, not areas like pesticide use, adding: "How can we protect consumers in Europe?"
Shouts rang out across the Commons.
"It as though a fog of self-doubt has descended", Johnson said.
"The problem is not that we failed to make the case for a free trade agreement of the kind spelled out at Lancaster House - we haven't even tried".
But, Johnson said, "in the 18 months that have followed, it is though a fog of self-doubt has descended" on the government.
"So, when you say, 'is it flexible?', it's not in the sense of they're going to wriggle away at it and we're going to accept it". In addition to the Netherlands and Ireland, this also includes Denmark and Belgium.
There are a raft of petitions online calling for the resignation of May, and public calls of no-confidence, both over her politics and Brexit.
Parliament plans to begin its long summer recess Tuesday after a feverish series of debates on Brexit policy.
