Contribution

As the House would expect, we went through a process. There was a due diligence exercise, and then there was security vetting by the security services. What was not known was the sheer depth and the extent of the relationship. Mandelson lied about that to everyone for years. New information was published in September, showing that the relationship was materially different from what we had been led to believe. When the new information came to light, I sacked him, but we did go through a due diligence exercise. The points that are being put to me were dealt with within that exercise. In response to the Humble Address this afternoon, I intend to make sure that all the material is published. The only exemptions are anything that would prejudice national security—my first duty is obviously to keep this country safe, and when we drafted Humble Addresses in opposition, we always included an exemption for national security—or that would prejudice international relations. You and the House will appreciate, Mr Speaker, that in the course of discussions country to country there are very sensitive issues of security, intelligence and trade that cannot be disclosed without compromising the relationship between the two countries, or a third country. So that I can be totally open with the House, I should also disclose that the Metropolitan police have been in touch with my office this morning to raise issues about anything that would prejudice their investigations. We are in discussion with them about that, and I hope to be able to update the House, but I do think I should make that clear to the House at this point, because those discussions are ongoing.
