The news that King Peter had married in wartime did much to discredit him with his people, and becoming very unsettled as it started to sink in that he might have sacrificed his throne for love, Peter became unusually open to British "advice" in early 1944. Churchill had announced in the House of Commons in May 1944 that Peter had dismissed Purić as Prime Minister and Mihailović as Chief of Staff and the new prime minister was Ivan Šubašić, when none of these things had actually happened. After a week of strong British pressure, Peter capitulated and on 1 June 1944 appointed Šubašić prime minister. The mandate of the new Šubašić government was to form a coalition with Marshal Tito's People's Liberation Movement. On 10 June 1944, Šubašić flew to the island of Vis to meet Tito for talks, and on 16 June 1944 it was announced that the Partisans were the only recognized agents of the government-in-exile in Yugoslavia and the governing bodies set up by the Communists were the provisional government of Yugoslavia. Šubašić did not consult with King Peter and presented the agreement with Tito as a "fait accompli" to the king. The cabinet announced by Šubašić was very left-wing and on 29 August 1944 Mihailović was dismissed as chief of staff. On 12 September 1944, King Peter went on the BBC to appeal to all his subjects to support Tito and warned that the "stigma of treason" would stick to those who refused this command. At the same time, Stalin, anxious to allay Western fears about the future of Eastern Europe, ordered a very reluctant Tito, in a meeting in Moscow, to allow Peter to return to Yugoslavia though with the advice that he "should slip a knife into his back at the appropriate moment".
