My right hon. and learned Friend has pointed out that the best-endeavours clauses in the withdrawal agreement impose a duty on both sides to proceed with the utmost good faith in seeking to achieve an agreement at some time in the future. He has said also that these are obligations that are judiciable and enforceable. As a practical lawyer advising the House, as he has kindly offered to do, will he tell the House whether this is a matter about which the House should be relaxed? Or should we proceed at our peril?
