Stojadinović initially intended to appoint Purić as Minister of Foreign Affairs, but he gave up on that plan at the insistence of the Royal court.

[3] Božidar Purić was appointed for the prime minister of the Yugoslav government-in-exile on 10 August 1943, succeeding Miloš Trifunović who resigned after constant disputes between Serbian and Croatian members of his cabinet.

Chetnik collaboration with Italians and the Germans, as well as fighting against the Partisan resistance movement caused the British to pressure the Yugoslav government to remove Mihailović from office.

[7] Purić's cabinet dispersed the "League of Majors", a group of inner circle advisers to King Peter headed by Knežević brothers.

[8] Radoje Knežević was removed from the position of Minister of the Royal Court and sent to Lisbon as chargé d'affaires by Miloš Trifunović.

Two aides-de-camp to the king, Vlastimir Roždjalovski and Svetislav Vohoska, were sent to parachuting training in a British base so they could be dropped to Chetniks in Yugoslavia, this, however never happened.

[4] It was decided that Bogoljub Jevtić should become Yugoslav ambassador to London and King Peter was given permission to marry Princess Alexandra which was opposed by the previous Prime Ministers.

[7][10] On 7 December 1943, Anthony Eden talked for the first time with Purić since the Tehran conference, where it was decided that Allies should support Yugoslav Partisans.

Even after this, the Purić government refused to remove Mihailović from the office which resulted in a complete breakdown in relations between pro-Chetnik officials who controlled Yugoslav government-in-exile and the British.

King met with the British ambassador to the Yugoslav government Skrine Stevenson during the next day, and he seemed ready to take Churchill's advice.

However, the king soon changed his mind, likely after talking with Purić, and on 17 April he sent an urgent letter to US President Roosevelt saying that dismissing his best Prime Minister and relieve Mihailović would mean committing an act of treason on his nation.
