Underground leaders of Poland's suspended Solidarity trade union have appealed to their supporters to suspend existing protest actions against martial law and prepare instead for a nationwide general strike, Washington Post correspondent Michael Dobbs reported.

The call for a change in tactics was made in leaflets circulating here. It reflected a recognition that while token strikes and street demonstrations may remind Poles of Solidarity's existence, they also serve as a pretext for greater suppression by the martial law authorities.

Government spokesmen, meanwhile, tried to dampen speculation that Solidarity leader Lech Walesa may be released from detention soon. The reports stemmed from an interview with Deputy Premier Jerzy Ozdowski who was quoted by the Cable News Network as saying that Walesa would soon return to a normal life in his hometown of Gdansk.

An official spokesman, who refused to be named, said Ozdowski appeared to have been quoted out of context and had meant to say that the government intended releasing Walesa if the process of political normalization in Poland continued without interruption. No specific time was set for the release, however.

Walesa's wife Danuta said she still did not know precisely where her husband was being held.
