To ask Her Majesty's Government, further to the remarks by Lord Pearson of Rannoch in the debate on the Brexit Withdrawal Agreement and Political Declaration on 14 January (HL Deb, col 96), whether it remains their position that "nothing is agreed until everything is agreed" in the Brexit negotiations.
Both the Withdrawal Agreement and Political Declaration have now been agreed between the EU and the UK and endorsed by leaders of the 27 Member States. The UK and the EU have been clear that the Withdrawal Agreement and the Political Declaration form a package, and that neither document can be considered final until both have been agreed.
The Political Declaration provides detailed instructions to negotiators that will seek to deliver a legal agreement by the end of 2020. Once the final deal has been approved by the House of Commons, the UK and the EU will then formally sign the Withdrawal Agreement which, after ratification on both sides, will enter into force as a legally binding international treaty.
