Sergei Grigoryants, editor of the journal Glasnost, has been sentenced to a week in jail following a KGB raid on his country home where dissidents were meeting to establish an opposition political party, his wife, Tamara, said Tuesday.

Tamara told Western journalists her husband was given a summary jail sentence for "resisting arrest." Five other members of the Glasnost staff were also detained. She said three of them were fiven five-day jail terms and two were released.Under Soviet law, the sentences could be handed down by a senior police official without court proceedings.

Mrs. Grigoryants said police and KGB agents searched their home where members of the Democratic Union were concluding a three-day meeting at which they established an opposition political party to challenge Communist Party rule.

"They broke the law by searching our home," she said. "They could have planted any type of evidence there."

Police confiscated about 70 copies of the latest issue of Glasnost and several hundred copies of previous issues, Tamara said.

Glasnost, a year-old dissident journal testing the limits of Soviet leader Mikhail Gorbachev's reforms, has not been officially registered as a newspaper nor has it been banned by government censors.

Dissident sources said about 70 members of the new Democratic Union, their ranks already depleted by arrests during the first two days of meetings, were allowed by scores of police and KGB agents to board a train to an outlying village for their third and final day of discussions.
