In terms of invoving Criminal Law, well I don't think we should go down that route.
However, if a court found for a complainant, then the apology from the newspaper should occupy the same number of column inches as the offending article.
So if " ''X' CAUGHT IN DRUG-FUELLED TAX EVADING SPY GAY SEX PROSTITUTE ORGY RAPE" occupies the front page aswell as pages 4, 5, 6, 7 and a special pull-out-and-keep centre section, then the apology should occupy exactly the same space - perhaps filled with a rather boring reproduction of the court's findings in full and a somewhat less-than-attention-grabbing front page - all irrespective of what else happens to be in the news on the agreed date of publication of the apolgy.
Then watch their circulation and advertising revenues fall for that edition.
The b*stards.
