Polish Communist Party leader Stanislaw Kania today assailed elements in Poland who seek to weaken the nation's links with the Soviet Bloc and asserted that Poland "is and will be the ally of the Soviet Union."

While not specifying his target, Kania condemned "allthose who, speaking of renewal, think about turning back our country from its socialist course, implementing a state of double authority and weakening our links with other countries of the socialist community." "Renewal" is the name give to the process of change advocated by the Solidarity free trade union federation.

The Polish leader made the remarks in a speech at the congress of the Democratic Party, a tiny group that, ostensidbly in coalition with the Communist and Peasant parties, governs Poland.Democratic leader Witold Mlynczak at the same session warned of possible outside intervention unless the Poles solve their problems "by political means and only by ourselves."

Earlier today, the government daily Zycie Warsrawy accused the communist leadership of weakness and indecision and said this was partly why Solidarity had turned political and militant.

Zycie Warzawy said in a front-page editorial that Solidarity was being forced to protest over discredited officials because the party was not quick enough in removing them itself.

In the city of Radom, south of Warsaw, ocal Solidarity leaders have threatened a strike to force the dismissal of officials held responsible for the suppression of a workers' revolt in 1976.

"In order to achieve a genuine leadership of society, the party must first of all square accounts with all who violated the three basic principles of the socialist system -- social justice, democracy and the rule of law," the paper said.

It also criticized the party leadership for failing to come up with real solutions to the country's serious economic problems and for dragging its feet over a new law on relaxing censorship.

Solidarity's Radom branch is demanding the resignation of the local party head, the governor and the police chief, who were all in office during the 1976 revolt there. State radio reported today the party chief in Radom had offered his resignation 10 days ago, and later today the Polish news agency reported that his resignation had been accepted. The Polish news agency PAP also reported the Polish Premier Wojciech Jaruzelski had accepted the resignation of Governor Roman Mackowski.

The union was also seeking disciplinary action against justice officials and judges responsible for the trial of about 50 workers arrested after the revolt, which was sparked by a protest over higher prices.

Union officials reported that its branch in Swietokryski, a neighboring region to Radom, had voted a sympathy strike on March 23 unless Random's grievances were settled. In a related development, the union reported the release from prison of a nationalist dissident, Wojciech Ziembinski, who was arrested last November after leading an illegal march here.
