Qatar World Cup organisers have published a 50-page document they say will guarantee the rights of the 55,000-plus migrant workers who will carry out construction of the tournament facilities.

FIFA had given Qatar 2022 until today to respond after the latest investigation into the treatment of migrant workers, ahead of a hearing at the European Parliament in Brussels on Friday.

A Guardian investigation last month claimed more than 185 Nepalese workers died in Qatar in 2013.

Human rights and labour organisations have criticised abuses of the kafala system where workers are unable to leave Qatar without their employers’ permission.

The document by the newly-named Qatar Supreme Committee covers many of the issues, outlawing the practice of middle-men operating a black market in providing cheap labour.

Workers will also be guaranteed the right to retain their passport and employers must pay their travel costs to return home at the end of the contract.

At least eight stadiums will have to be built for the 2022 World Cup and 32 training camps for the countries involved.

Hassan Al Thawadi, secretary general of the Supreme Committee, said progress in workers’ rights was already well underway.

Qatar said it had co-operated with the International Labour Organisation in drawing up the document
