Bulgaria's Grand National Assembly voted late Tuesday night to order the interior ministry to turn over all its files on members of parliament to a special parliamentary committee within one week.
Opposition sources said this week as many as one-fourth of Bulgaria's members of parliament, including leading dissidents under the former Communist regime, could have been secret police informers or agents.The vote came after public accusations earlier Tuesday that Petar Beron, chairman of Bulgaria's opposition coalition, the Union of Democratic Forces, was a secret police informer.
Beron resigned as coalition leader Sunday, saying he wanted to return to his profession as an entomologist but kept his parliamentary seat.
Earlier in the day, President Zhelyu Zhelev denied reports he has files showing Beron was a secret police informer but said "perhaps" that was the reason for his resignation.
Under the terms of the vote Tuesday night, the special parliamentary committee will have until the end of the seven-day period to devise a procedure for dealing with the secret police files.
Approval of the measure follows growing public speculation and rumor over links between members of Bulgaria's parliament and the Sixth Department of the Derzhavna Sigurnost, Bulgaria's secret police, which was formally abolished last year.
Interviewed by the British Broadcasting Corp. in Milan, where he was attending a scientific conference, Beron called for all files on deputies to be turned over to parliament.
Beron was touted as a likely candidate for premier after last week's resignation of Andrei Lukanov and his government of former Communists following four days of protests over worsening food and energy shortages.
