The minister for Brexit has said the Government may continue to pay into EU coffers even after leaving the bloc in a possible deal to retain access to the free market.
David Davis told MPs the Government was willing to consider making contributions to ensure that it continues to get access to tariff-free trade.
Any such move will enrage Leave campaigners who have pushed for a so-called 'Hard Brexit' which would end freedom of movement and cut all formal ties to the bloc.
Mr Davis made the disclosure after Labour MP Wayne David asked: "Will the Government consider making any contribution in any shape or form for access to the single market?"
He said that he was willing to look at all the options in an effort to "get the best possible access for goods and services to the European market".
"If that is included in what you are talking about then of course we would consider it," he added.
Mr Davis also faced fresh accusations that the government has failed to be transparent over its plans for an exit.
Hilary Benn, Labour chairman of the Commons Brexit Select Committee, said MPs were "getting a little fed up with being told nothing".
Labour's Heidi Alexander added ministers appeared to be failing to formulate a clear blueprint.
She asked: "Don't the British public deserve better than this embarrassing charade?"
Mr Davis hit back saying that the Government will make its position "very clear" by the time in triggers article 50 early next year.
He said that point was still "four to five months" away and that when negotiations begin the Government's position will be "very clear".
