STOCKHOLM, Dec. 17.—A telegram to the Social-Demokraten says that troops of the Ukrainian National Union are besieging Kiev and have reconquered the whole of Ukraine. The political situation everywhere is said to be favorable to the National Union. Another telegram says that the Union has proclaimed a federative union of the whole russian democracy. The Social-Demokraten comments that the Ukrainian National Union has on its side the sympathy and support of the Allies. It says it is of the greatest importance that all efforts should be made to support those who are working for democracy and against Bolshevism. The paper also points to the English support of the democratic Government in Esthonia, and concludes that the Allies’ policy in the East is in full accord with clear democratic principles.
