Sir William Cash (Stone) (Con): The Government have just presented three White Papers to Parliament under their self-imposed legal duty to provide information under the European Union Referendum Act 2015. The Minister for Europe, during proceedings between the two Houses, gave me an undertaking that the Government information under that Act would certainly, as he put it, be accurate and impartial. The three recent White Papers are not. My right hon. Friend the Prime Minister is the enforcer of the ministerial code, which demands that Ministers give accurate information to Parliament. Will he issue instructions to Foreign Office Ministers to review and correct those White Papers?

The Prime Minister: First, let me say to my hon. Friend that we believe in the sovereignty of Parliament. Parliament dictated that those documents would be published, and that is why they are being published. On the question of their content, their content has been prepared by civil servants under all the appropriate codes. If he does not agree with some of the content, I would say to him and to other colleagues: challenge the content. Have an argument about the content. Stop arguing about the process.
