EU ministers have finalised their preferred timeline for the Brexit transition period, saying they want it to last from March 2019 until December 31, 2020.
The official spokesperson for Theresa May has said whilst there is "broad agreement" on the principle of the timeframe there are still disagreements in its "specific detail."
The spokesperson said there will be "negotiation on what the implementation period looks like" and "formal directives will be released this afternoon."
He added there will "naturally be some distance in the detail of our starting positions."
Senior UK ministers met today (January 29) to discuss the matter and whether the UK should be entitled to start talking to other countries about trade negotiations whilst in transition.
It is hoped the transition window will mean disruption to holidays, businesses and security is kept to a minimum after Brexit, according to the BBC.
The implementation period should also allow for final arrangements between the UK and EU to be mapped out.
Despite Brexit being formally triggered next March, it is likely that the UK will be obliged to adhere to the rules of the customs union and single market during the transition period, and accept the free movement of EU citizens.
But it is thought the UK won't have a vote on EU matters during this time, despite still being influenced by its rules, including those created after March 2019.
