Western delegates are supporting an early and lengthy recess of the Conference on Security and Cooperation in Europe yesterday after two stormy days of debate on the Polish crisis.

Pierre Aubert, foreign minister of neutral Switzerland, which has played a key role during the past 17 months of the conference, sharply criticized the military government in Poland. He said that in the present crisis in East-West relations "we believe that the only reasonable solution is to quickly suspend the Madrid meeting and to return here after an interruption of several months."

Ambassador Javier Ruperez, chief of the delegation of Spain, which is host to the conference, said the Swiss desire for a suspension of the conference had been "well received by Western delegations."

Three foreign ministers, from Norway, Turkey and Switzerland spoke yesterday. All continued the West's attack on Poland and the alleged role of the Soviet Union in the Dec. 13 imposition of martial law.

The three foreign ministers had been on a list to speak Tuesday but Poland, the chairman under a rotating presidency rule, stopped the Western attack that morning. Several more Western foreign ministers are scheduled to speak Friday.

Haig, calling Tuesday's disruption of the conference an "unfortunate misjudgment" by the Soviets, predicted that the incident will increase denunciations of the military takeover in Poland.
