My hon. Friend is absolutely right. The business community and citizens are clear that they want the certainty that the deal offers. They want the implementation period to allow investment to be made and planning to proceed. Given the risk of uncertainty that will result from the uncharted waters we will enter if the deal does not go ahead, it is time for Members to look again at the deal and at the complex set of terms within the withdrawal agreement and not let the perfect be the enemy of the good.
