News Summary; TUESDAY, DECEMBER 8, 1981
International Polish union leaders were accused by the authorities of calling for the overthrow of the Government. The Warsaw radio transmitted a tape recording made at a closed meeting of union leaders last Thursday in which Lech Walesa, the union chairman, asked for a ''confrontation'' and another labor leader urged the overthrow of the regime. Mr. Walesa confirmed in an interview that he had made his remarks but said they had been taken out of context. (Page A1, Column 2.) Possible measures against Libya were discussed by President Reagan and his top advisers. Such measures might include an embargo against the import of Libyan oil and a ban on travel by Americans to Libya. (A1:1.)
