in February by the Siberian Regional Duma, a body which had been chosen on the basis of universal suffrage and which, like the Constituent Assembly, had been dispersed by the Bolsheviki." Derber didn't agree with this result and his PSG on the meeting at Vladivostok was renamed as Provisional Government of Autonomous Siberia (PGAS). PGAS and new PSG didn't recognize each other and claimed themselves as the only government of Siberia, but Derber's government didn't have armed forces. In a short time, Derber resigned and left Vladivostok; his successor was I.A.Lavrov from Socialist-Revolutionary Party. In September 1918, the Pyotr Vologodsky, representing the Provisional All-Russian Government, traveled to Eastern Siberia according to Chamberlin, "...and obtained the abdication of the phantom Derber Cabinet in Vladivostok."
