"The prime minister has been clear that we are making good progress on the future relationship and 95% of the withdrawal agreement is now settled and negotiations are ongoing," the spokesman also said, as quoted by the Sky News.
According to the newspaper, May is also planning to reach an agreement on the EU-UK post-Brexit economic partnership, as she aspires to ensure free trade between London and Brussels.
The UK government will reportedly discuss May's plan on Tuesday, as London aspires to promptly reach sufficient progress in Brexit talks, thus opening door for a EU summit for finalizing the details to be held later in the month.
The United Kingdom voted to leave the European Union in a referendum in June 2016 and is expected to do so by late March 2019, while there are still certain stumbling blocks that impede talks, namely, the Irish border and the post-Brexit UK-EU economic relations.
While European Council President Donald Tusk said in September that an extraordinary summit would be called for November 17-18 to finalize and formalize the EU-UK arrangement if sufficient progress in talks was reached, the EU leaders are currently not planning this extraordinary summit.
