Premier League leaders urged to join fight for better working conditions as they prepare for Fifa Club World Cup match

As Liverpool fans stream into Qatar to watch the Fifa Club World Cup next week, it will be easy to forget the thousands of workers from the poorest countries in the region who have toiled for years to construct its glittering buildings.

When they take their seats at the Khalifa International Stadium, where Liverpool will play their semi-final match, they may not realise that scores of workers who refurbished the stadium were housed in filthy, overcrowded accommodation with an ever-present stench of raw sewage.
