Methodology 6. There has been widespread public interest in, and concern about, a number of gatherings taking place in No 10 Downing Street and Whitehall during periods of nati onal Covid restrictions, where their necessity for work purposes has been open to question. My task has been to establish, as far as possible, the facts surrounding these gatherings. 7. In carrying out my investigation I have been supported by a small team o f senior civil servants in the Cabinet Office, who have no connection with the events under examination and who are bound by the requirements of the Civil Service Code. We carried out interviews of over 70 individuals , some more than once, and examined relevant documentary and digital information, such as emails ; Whatsapp messages; text messages; photographs and building entry and exit logs . This has also included searches of official records. As such, extensive substa ntive factual information is now available and has been compiled by me and my team to fulfil my obligation to establish the facts . T he i nvestigative work is now ess entially complete . 8. The Treasury Solicitor and Daniel Stilitz QC have provided independent advice as to the process. 9. It is not for me to make a judgment on whether the criminal law has been broken; that is properly a matter for law enforcement. In line with my terms of reference I have been in regular contact with the Metropolitan P olice as my work has progressed in orde r for them to take decisions on the gatherings under examination, including whether to launch their own investigation.
