Daily Express did not first publish the so-called Zinoviev letter, a probably forged letter in which Grigory Zinoviev, the chief of the Comintern, was alleged to order British Communists to infiltrate the Labour Party and the military, which was published in the Daily Mail instead. However, after the Zinoviev letter was published, Beaverbrook had the Daily Express in its coverage of 1924 election associate the Labour Party with Communism. The cartoons which the Daily Express published tended to depict Communists as alien, dirty, hairy, and unkempt thereby associating them with popular stereotypes of the poor. In foreign policy, Beaverbrook promoted a policy known as "empire isolationism", namely that Britain should devote its interests to the British empire, but be otherwise disengaged from the rest of the world. A recurring theme of Beaverbrook's newspapers was that Britain was not a European nation, and should have as little to do as possible with the affairs of Europe. Likewise, Beaverbrook was opposed to British membership in the League of Nations and in a 1923 leader advocated giving up the Palestine Mandate (modern Israel), which Britain held as the administrating power for the League, under the grounds that Palestine was more of a debit than a credit for the British empire. A typical statement from Beaverbrook was: "The British empire exists for the British race. It is our heritage. Let us cultivate it, defend it, cherish it, and make it great, rich and strong in righteousness, an example and object lesson for the rest of mankind". In 1925, Beaverbrook wrote: "In the Empire and not in Europe our future lies and the Daily Express has never failed to preach the Imperial doctrine in good or bad times. The Daily Express believes that the British Empire is the greatest instrument for good the world has ever seen". Beaverbrook believed that protecting the greatness as he saw it of the empire could be best accomplished via "splendid isolation" as he consistently argued for an isolationist foreign policy. In 1925, Beaverbrook via the Daily Express was strongly opposed to the Treaty of Locarno under which Britain "guaranteed" the current borders of France, Belgium, and Germany along with the permanent demilitarised status of the Rhineland as involvement in European conflicts where no British interests were at stake. Reflecting his origins, Beaverbrook always thought in terms of the British empire rather than of Britain, and he had an essentially
