That very challenging question is not dissimilar to the questions that I asked the Government and Prime Minister about what enforcement mechanism there will be to ensure that “best endeavours” as referred to in the withdrawal agreement will be implemented. In answer to a parliamentary question from me, the Minister replied on 22 November:
“The reference to best endeavours in Article 184 of the Withdrawal Agreement is a legally binding commitment that requires the United Kingdom and the EU to conduct themselves so that the negotiations on the future relationship are meaningful. It prohibits inflexible or obstructive behaviour and obliges the parties to pay reasonable regard to the interests of the other party.”
So in answer to the hon. Gentleman, that is the precedent that would be established. If he thinks that that is full of clarity, then I am sure he will be eager to support my amendment.
