British Prime Minister Theresa May will make a keynote speech next Friday on the UK's relationship with the EU after Brexit following a "very positive" meeting of her senior ministers.
Her spokesman said: "The prime minister will be setting out more detail of the government's position".
Ahead of the speech, Mrs May will meet European Council President Donald Tusk on Thursday.
Confirmation of the much-anticipated speech comes after Mrs May gathered around a dozen of her senior ministers for an "away day" at her country retreat in Chequers yesterday.
Their discussions lasted eight hours as they sought to thrash out their considerable differences on how closely aligned Britain should stay with the EU once it leaves the single market and customs union.
Mrs May's speech is expected to take place somewhere in Britain, after she chose Florence in Italy for her last big Brexit address in September.
Health Secretary Jeremy Hunt said the cabinet had agreed to pursue a Brexit policy that would put Britain outside a customs union with the European Union but match Brussels’ rules in certain sectors in an attempt to achieve "frictionless" trade.
He revealed that the government was putting itself on a collision course with Tory Brexit rebels who are backing an amendment to the Trade Bill, which would mandate the UK to form a customs union with Brussels on leaving the EU.
The move presents an increased danger to Mrs May because shadow foreign secretary Emily Thornberry said Labour now backs a customs union that would look "pretty much like" the current one after withdrawal.
Mr Hunt, who did not attend the Chequers meeting, said ministers agree that Britain must not be part of a customs union as it should have the right to strike free trade deals with other countries, and claimed "frictionless" trade was still possible without one.
He told BBC Radio 4's Today programme: "If we were a part of the customs union we wouldn't be able to negotiate trade deals independently with other countries and we wouldn't have full sovereign control of our destiny as a nation.
"But what we want is frictionless trade and we want to find a different way - customs union is one way of getting frictionless trade but it's not the only way - and what we're saying is we want to achieve frictionless trade by agreement between two sovereign bodies - the United Kingdom and European Union."
Tory Brexit rebel Anna Soubry, who has tabled the customs union amendment, said she has cross-party support and called on Labour to back it, tweeting: "It would be in the national interest if the Government & official Opposition also backed it."
Labour leader Jeremy Corbyn is to announce a competing vision of how Brexit should work in what is being billed as a significant address on Monday, after some backbenchers called for more clarity from the leadership.
Mrs May was also facing pressure from the Brexiteer wing of her party amid reports that EU migrants who arrive in the UK during any transition period will be allowed to stay permanently.
Jacob Rees-Mogg, who chairs the European Research Group of backbench Tory Eurosceptics, said such a U-turn would be "unconscionable".
The Tory MP told Today: "Mrs May said when she was in China that she wasn't going to do that and that people who came after we'd left would be subject to different conditions, which seems absolutely right.
"You've got to remember we are leaving the European Union on March 29 (2019), we will be out of the treaties on that day, we will not have any say in the rules that are made and therefore people who come after that day ought not to be allowed to have the full and permanent free movement rights.
"That would be quite wrong, and they will know the conditions on which they come, which is important, so it's fair to people who come after that date.
"And I'd be astonished if Mrs May would make U-turn of that kind; she is a lady of great backbone and for her to kowtow to the European Union is I think unconscionable."
