But as leadership contenders Boris Johnson and Jeremy Hunt both stress how they will accept a no deal if it means leaving on deadline day, Ms Rudd appears to have shifted her stance on the scenario.
"It is not right that civil servants' careers and prospects should be dragged into the political agenda", Johnson said.
'He has basically thrown this fantastic diplomat under the bus to serve his own personal interests'.
If I am not mistaken, that schedule can be sped up if Hunt would step out.
"I think everybody is fed up with delay and I think the idea of now consecrating this decision to the judiciary is really very, very odd indeed".
Speaking during the debate, Mr Grieve said he did not think democracy would survive Parliament being prorogued to allow for a no-deal Brexit. "They can't be concerned for the sovereignty of Parliament except when it is inconvenient to Mr Johnson".
Finally, I see in Boris Johnson a man with a vision.
"Since the leak of official documents from this embassy there has been a great deal of speculation surrounding my position and the duration of my remaining term as ambassador", he wrote.
"Can confirm I am not said candidate".
"I think there may be some question about how exactly that money is dispensed, by whom and I would want to make sure that there was a strong Conservative influence on the expenditure of that £350 million, or whatever the sum is", he added.
'Good government depends on public servants being able to give full and frank advice'. "I hope the house will reflect on the importance of defending our values and principles particularly when they are under pressure".
"It is our most important diplomatic relationship", he said. He said it was crucial to fix the damage done by the leak because USA ties were "our most important diplomatic relationship".
He also reportedly chose to stay away from a meeting between International Trade Secretary Liam Fox and the president's daughter, Ivanka, to avoid any potential embarrassment.
