The problems at Hollinger International [H-Intl] are not confined to the alleged misdeeds of former chairman/ceo Lord Conrad Black.

The newspaper publisher's audit committee revealed Tuesday it had uncovered further circulation overstatements beyond those already disclosed at the Chicago Sun-Times.

Over-creative sales practises have been identified at the Jerusalem Post plus two suburban Chicago newspapers, the Daily Southtown and The Star – which in each case were used by advertising sales executives to justify ad rates.

Hollinger said it plans to make restitution to all advertisers affected and intends to take a charge of $27 million (€21.9m; £15.14m) to cover these unforeseen costs.

The company also revealed that circulation inflation at the Sun-Times had been endemic for years, employing such scams as manipulating the counting of unsold newspapers and by using paper recycling proceeds to buy newspapers.
