Senior ministers have agreed to make a Brexit deal with the EU by the end of November, sources say.
"Everyone saw the difficulties of leaving it longer," a senior cabinet source told the BBC.
Meanwhile, the BBC has come to a close.
It includes speeches from Theresa May and support from business figures and foreign leaders.
The notes, which dismissed the cabinet, have been dismissed.
Sources say they have a deal to do this month and they agree.
Deal presentation plans?
The UK is due to leave the EU on 29 March.
If you can not make it back to the EU in time, Mrs May wants to persuade her party – and the rest of Parliament – to support it in a Commons vote.
"The narrative is going to be measured success, this is good for everyone but not all champagne corks popping."
They refer to a speech by Mrs. May to the CBI, saying: "We have delivered on the referendum."
"To top up 25 top business voices … and lots of world leaders Japanese PM to tweet support for the deal".
It would take less than three weeks to get through.
But a Government Spokesman said: "The Missing and Childish Language in this document should not be clear.
"You would expect the government to have plans for all situations – to be clear, this is not one of them."
The spokesman did not come there were advanced plan for building a deal if and when it is concluded.
Earlier No 10 said the Prime Minister assured ministers that the cabinet would meet before the UK agreed to make any deal on the terms of the UK's exit.
The withdrawal from the bankruptcy in Ireland is the best thing to do.
There is disagreement on this "backstop" should apply to Northern Ireland, or the whole of the UK – and on it should be time-limited or revoked by the UK.
When it no longer applied.
Attorney General Geoffrey Cox has been given the legal position for an independent review mechanism for the backstop.
He is believed to have been trapped "in limbo".
The Irish border is due issue after the Brexit it wants to become the UK's country border with the rest of the EU, which has a single market and customs union.
And there have been warnings and the peace process in Northern Ireland.
EU negotiator Michel Barnier told a Belgian broadcaster that the Irish border remains the hurdle to overcome. If enough progress is made, he said, he will recommend that a summit is finalized.
Meanwhile, the government has published the criteria for allocating scarce permits for British truckers who need to drive in the EU after Brexit.
The permits will be shared based on: vehicle emissions, number of international journeys in the previous year, number of international journeys as a percentage of all journeys, type of goods transported and an element of opportunity.
BUT might be required after the future economic partnership agreement, depending on the type of deal.
