Polish police raided the Warsaw headquarters of the labor coalition Solidarity yesterday and seized a classified government document on policy toward dissidents.

Elsewhere in the capital, the country's agricultural crisis was being debated in parliament, where a member called for the ouster of two ministers and an official announcement spoke of an impending major policy change.

A spokesman for Solidarity, the country's new independent labor union, said about a dozen secret police and uniformed detectives raided the Warsaw area Solidarity office. "They searched through all the rooms in the office and in our printing section," he said. No arrests were immediately announced in the first such raid on a Solidarity office.

The spokesman said the police were searching for a copy of a secret 13-page document issued by the Polish prosecutor general Oct. 30 tracing history of government policy toward dissidents since the massive strikes in August and also detailing methods used by authorities to combat "antisocialist elements."

"They found one copy of the document and took it away," the spokesman said.

In the parliament, long a rubber stamp for the Communist Party, delegate Jerzy Bukowski called for the dismissal of Agriculture Minister Leon Klonica and Food Industry Minister Jan Zaleski. They were among several officials giving a gloomy picture of agricultural prospects.

Klonica, in a turnabout, said more funds would be diverted to private farms, which have been more productive than the preferentially treated state farms.
