MOSCOW, March 21--Secretary of State Marshall asked the Council of Foreign Ministers today to authorize the Germans to establish immediately a provisional government as the first step toward creating a federalized Germany.

Marshall's request was included in a proposed three-point plan of procedure for setting up a German government which he said should be started "at once so there will be properly constituted German authorities" to carry out the terms of the peace settlement being drafted here.

British Foreign Secretary Ernest Bevin earlier had submitted a similar proposal but in much greater detail, and warned Russia that Britain would not stand for any "one party" system in Germany.

Although not mentioning communism by name, Bevin declared that the British "do not believe Germany should merely change from the Nazi party to another party, nor Nazi ideology to some other ideology."

The inference was clear, since the Russians in the Eastern Zone of Germany insisted on, and created, a one party system called the Social Unity Party by a forced merger of the Communists and Socialists.
