On a point of order, Mr Speaker. I think the Secretary of State has got confused between the ruling of the Court of Justice and the preliminary opinion of the advocate-general. It was the preliminary opinion of the advocate-general that suggested that once article 50 was revoked, it could not be implemented again, whereas the opinion of the Court of Justice does not say that. Given that it is a judgment of the highest court in Europe, how can I put the record straight? The Secretary of State seems to have misunderstood the judgment.
