High fashion brand Prada has become the latest target for labour rights groups who organised a protest outside its store on London's Old Bond St at the weekend, alleging worker abuses at its Turkish leathergoods supplier Desa.

Two workers from Turkish factories that supply Prada and other luxury brands are also touring Europe to try to raise awareness of what they claim is "exploitation and union repression."

The will be speaking with government officials, trade unions, and NGOs in Italy, France and Spain, including a meeting with El Corte Inglés which sources from the factory.

The protest is being organised by the Clean Clothes Campaign, an alliance of organisations in 12 European countries that strive to improve working conditions in the global garment industry.

Problems began last year, when workers began joining the Turkish leather workers union Deri Is in protest at long hours, low wages and appalling conditions.

The factory retaliated by dismissing union leaders and members, and running a campaign of harassment and intimidation against the union.

The Clean Clothes Campaign has been campaigning since November in support of the company's 700 workers. 

It has also called on the factory's customers - including Mulberry, Nicole Fahri (owned by French Connection), Luella, Samsonite, and Aspinalls of London - to take responsibility for the workers who produce their goods. 

Other brands involved in the case, including the Spanish giant El Corte Ingles and British high street retailers Marks and Spencer and Debenhams, have contacted Desa to raise concerns about the case.
