The right hon. Lady is right. Businesses want the certainty of knowing where they will stand so they can plan for the future. Two things are important. It is important that we bring the acquis into UK law through the great repeal Bill, so that on the day we leave everybody knows those rules still apply and everybody knows where they stand. It is also right that it is a tight timetable to get agreement on our future relationship. There will need to be an implementation period to ensure that that is put into practice in a way that makes practical sense for businesses and Governments.
