Davis told the Commons Select Brexit Committee today that Britain should be able to negotiate its departure from the EU and a new trade deal within 18 months of triggering Article 50.
When asked about when the government planned to publish its plan for Britain's exit from the EU however, the Brexit secretary said, "It won't be next month."
"The policy work is still under way and there are quite a few decisions that have to be made," he added.
According to Davis, government officials are still analysing 57 different areas which are likely to be discussed during the negotiations, with home affairs and justice dominating the agenda.
The minister said he wanted a “smooth and orderly” EU exit with the “minimum of disruption” and “maximum market access” to UK businesses.
Davis revealed there are four possible outcomes for the UK after it leaves the EU. These are being fully in the customs union; fully out; partially inside (being inside the customs union but outside the single market); and being outside the customs union but with customs arrangements.
He also suggested that new immigration policies could be decided after the UK leaves the EU and added that the UK could still be bound by the decisions of an international arbitration body similar to the European Court of Justice even after leaving the EU.
He also told the committee that he would be open for a transitional deal “if it’s necessary and only if it’s necessary”.
“But the British people want this done with some degree of expedition, they want it done properly and soon and that is what we are trying to do,” he added.
Last week, Davis suggested that the UK could consider paying for access to the EU single market after Brexit. In the committee hearing on Wednesday, the minister said he wanted to keep all options open.
Davis also suggested that the government was looking at the Norway/Sweden border as a possible model between Ireland and Northern Ireland.
