 Since the Government has lost most support on the international scene after the break-off of Andrija Radović, Popović worked actively and hardly to regain the prestige for King Nicholas.He tried to persuade the Montenegrin consul to lobby Nicholas' policy in the United States, however he has already declared loyalty to Radović's Committee for Unification.With the liberation of Montenegro from the Central Powers' occupation by the Serbian armed forces after the break through the Balkan Front, Popović attempted to secure the return of Nicholas and the Government to Montenegro on 16 November 1918 at the British Court, but this attempt has met only refusal.
