Britain has no overall plan for Brexit and a negotiating strategy for leaving the European Union may not be agreed by the government for six months, a leaked memo suggests.
The memo, seen by The Times and the BBC, also warns that the government is working on 500 Brexit-related projects and could need 30,000 extra civil servants.
However, there is still no common exit strategy "because of divisions within the cabinet," the document adds.
The memo, dated November 7, also criticizes Prime Minister Theresa May for her tendency of "drawing in decisions and details to settle the matter herself."
A government spokesman said it "didn't recognize" the claims made in the memo, which was prepared for the Cabinet Office by an unnamed consultant.
May hopes to trigger Article 50 of the Lisbon Treaty, which kicks off two years of talks to leave the EU, by the end of March.
