The Umbro sportswear company will be accused this week of using sweatshop labour as it tries to complete a GBP200m stock-market flotation. Labour Behind The Label, a campaign group that counts Oxfam among its members, claims that Umbro's suppliers are mistreating workers. Such an attack just before the Euro 2004 football championship could hurt Umbro, which supplies the England team with kit and uses England and Liverpool striker Michael Owen as its frontman. A former employee of an Umbro supplier will fly to Britain to describe working conditions in an Indonesian factory.
