The four amendments to the crucial Customs Bill were put down a day before Thursday's publication of a White Paper setting out the British prime minister's plans, which infuriated Leavers and prompted the resignation of Cabinet ministers Boris Johnson and David Davis.
"Top-level cabinet resignations usually spell trouble for a government and Boris Johnson's might well have led to a leadership challenge, but May appears to have emerged unscathed from a meeting of her party, for now", said Al Jazeera's Jonah Hill, reporting from London.
On Monday evening, Johnson was replaced as foreign secretary by Jeremy Hunt, who in turn was replaced as health secretary by Matt Hancock, as the prime minister embarked on a reshuffle to shore up her position. Negotiations are expected to conclude in October before the United Kingdom leaves the world's largest trading bloc.
The National Sheep Association (NSA) has welcomed the decision to appoint Dominic Raab as the new Secretary of State for the Department for Exiting the European Union (DExEU).
When asked directly if Trump would meet Johnson, U.S. Ambassador in London Woody Johnson told BBC Radio: "I'm not sure". Mr Davis resigned late on Sunday night (8 July), explaining that Prime Minister Theresa May had "given away too much too easily". "And that's a unsafe strategy at this time".
She said: "He talks about resignations, can I just remind him, I think he's had 103 resignations from his frontbench, so I'll take no lectures from him". But within 48 hours of their publication, Davis had quit, saying she had already given too much away to the European Union, and Johnson followed. It concluded with an announcement of a strategy that sought to allay some concerns in Brussels and within the business community over trading links.
"Being tied to European Union regulations and the European Union tying our hands when seeking to make new trade agreements will be the worst of all worlds", wrote the Mansfield MP, who voted remain in a constituency where more than 70 per cent of voters opted to leave.
Hopes dashed, England fans taste bitter defeat once again
It would have been the nation's first final since they won in 1966 but an extra time goal from Mario Mandzukic left dreams shattered.
A third amendment would require the government to sign up to having a separate Value-Added Tax regime from the EU, while a fourth would oblige the PM to creating primary legislation if she wanted to remain in the EU's customs union.
As the minister responsible for the Brexit negotiations, Mr Davis was a key voice in the debate in the UK.
"The general direction of policy will leave us in at best a weak negotiating position and possibly an inescapable one", he said in his letter.
Bridgen then called the prime minister's promises regarding Brexit negotiations a "pretence and a charade".
May's personal authority was badly damaged after she called a snap election previous year to strengthen her hand in Brexit talks but instead she lost her parliamentary majority, meaning she has to rely on a small Northern Irish party to govern.
Securing a U.S. -UK deal post-Brexit is something both Trump and May's government have heralded as being a major benefit of leaving the EU.
"With our leave date fast approaching we have no time for the mechanisms of a leadership challenge", he said.
