Prosecutors in Milan Wednesday urged prison terms of two years and six months for Italian fashion designer duo Domenico Dolce and Stefano Gabbana for allegedly dodging around a billion euros in taxes, Italy's AKI news agency reported.
The pair are on trial with five other people including company board member Cristiana Ruella and the designers' accountant Luciano Patelli over the tax evasion claims which date back to 2004.
Prosecutors reportedly asked for a three-year jail term for Patelli.
Dolce and Gabbana, whose clients include Beyonce and Madonna, deny the charges, AKI said.
The report said Dolce and Gabbana allegedly used a Luxembourg-based company in 2004 and 2005, to dodge taxes owed to the Italian state.
The investigation began after a tax inspection of the company between 2007 and 2010.
