Polish leader Stanislaw Kania acknowledged in a speech published yesterday by the official news media that there were divisions within the ruling Communist Party. He said the crisis in the country was not yet over.

Speaking at the closing session of the party's Cental Committee meeting, which ended Monday, he also said the party would honor its commitments to labor leaders over formation of the Soviet Bloc's first free labor unions.

Kania said the millions of nonparty supporters of socialism could feel what he described as "the bitter taste of the crisis that swept across Poland and which has not yet come to an end."

Hinting at still unresolved conflicts within the party between hard-liners and reformers, Kania said there were differences in approach, appraisals and proposals during the committee meeting, which fired eight of its full members and two deputies and promised a campaign against corruption.

Kania said the new free labor unions would have to conform to the socialist state.

"We shall do everything to maintain the political unity of the trade union movement so that the whole movement, although organizationally divided, remains socialist in character," he said.

He made no reference to "antisocialist forces," a phrase recently used to condemn tendancies in the new labor union movement.
