Mr Tusk said in Buenos Aires Friday morning: "Many leaders will certainly have questions about Brexit, therefore let me say this". "This is about what is in the national interest".
"I think it is important members of parliament focus on the nature of this vote".
Dr Fox was reported to be among a group of five Cabinet ministers seeking to tweak Mrs May's Withdrawal Agreement before MPs vote on December 11.
The amendment, put down by a group of committee chairs, including Labour's Hilary Benn and prominent Tory Sarah Wollaston, calls for the Commons to be able to express its views about what should happen if Mrs May's deal is voted down.
The latest minister to quit British Prime Minister Theresa May's government because of Brexit said Saturday that the prime minister's divorce agreement with the European Union would leave Britain outnumbered and outmaneuvered in future negotiations.
In the strongest comments yet that the bloc was unwilling to renegotiate further, European Council President Donald Tusk said the proposed deal was the best one possible.
In Buenos Aires, she'll set out what Brexit means for Britain's trading relationships around the world, her office said.

He told the BBC this morning: "There is a blocking minority in the House of Commons for nearly every possible option which means that letting the people decide, now that we know more, might be the most sensible path for both Leavers and Remainers".
Dr Fox is expected to say: "The withdrawal agreement and the political declaration will not please everyone, and we have had some tough choices to make".
If every opposition MP voted against, and they were joined by the 18 Tory MPs who have said they will also oppose it, this alone would be enough to defeat the deal. "We don't see any alternative coming forward from the Labor Party". People need to have some clarity about that... "What I see from Labour is an attempt to frustrate what the government is doing to deliver Brexit for the British people. That is actually a betrayal of the British people". "We will be explaining to members of parliament why we believe that this is a good deal for the UK", May told reporters on the plane to the G20 summit in Argentina when asked if she had a back-up plan. "We will be telling MPs why we believe this is a good deal for the United Kingdom because it is a deal that delivers on the Brexit vote". "It says we will be able to do those trade deals, and we will be able to do them with the U.S. and others".
Mrs May also accused Labour of pushing the United Kingdom towards a damaging no-deal Brexit by seeking to block her deal without offering a workable alternative.
Dr Fox said that reactions to Whitehall analysis showing that withdrawing from the European Union without an agreement would have severe economic consequences had been "overblown".
With scores of backbench Conservatives threatening to rebel in the historic "meaningful vote", Mrs May might have to rely on Labour votes and abstentions to save her Brexit deal.
May also received support from Environment Secretary Michael Gove, a key Brexit-backing minister, who wrote in the Daily Mail newspaper that lawmakers should back the deal rather than hold out for a "perfect plan".
