Dolce & Gabbana reportedly threatened to pull $20 million of magazine advertising over a planned expose.

Design duo Domenico Dolce and Stefano Gabbana - who were fined $470 million and sentenced to 18 months in jail after being found guilty of tax fraud last year - were upset US publication Vanity Fair are planning a feature on their financial woes and called Vogue Editor-in-Chief Anna Wintour, who is also artistic director at publishing group Condé Nast, in a bid to have the article pulled.

The pair also threatened to remove their advertisements from all publisher's titles if the proposed article wasn't axed, the New York Post newspaper's Page Six column reports.

However, Anna refused their request, though she, along with Vogue writer Hamish Bowles, was a guest at D&G's extravagant show in Capri last month, and it got rave reviews in the publication.

The editor also got interview time with the designers ''as a way of appeasing them without mortgaging the journalistic integrity of Condé Nast over killing the piece.''

A source added: ''She went to save the advertising.''

The fashion house continue to advertise in GQ, Allure, Details, Vogue and Condé Nast Traveler - but doesn't advertise in Vanity Fair.

A spokesperson for Vanity Fair said: ''We don't comment on whether we are or are not working on a story.''
