Special Branch, the intelligence division of the Metropolitan Police, maintained a file on Orwell for more than 20 years of his life. The dossier, published by The National Archives, states that, according to one investigator, Orwell had "advanced Communist views and several of his Indian friends say that they have often seen him at Communist meetings". MI5, the intelligence department of the Home Office, noted: "It is evident from his recent writings—'The Lion and the Unicorn'—and his contribution to Gollancz's symposium "The Betrayal of the Left" that he does not hold with the Communist Party nor they with him."
