Norway’s sovereign wealth fund has banned all holdings of shares in British security services company G4S because of the risk of human rights violations against its workforce in Qatar and the United Arab Emirates...

G4S, which is listed on the FTSE 250, provides security services in more than 90 countries, but the Council of Ethics focused on its “extensive use” of migrant workers from India, Pakistan and Nepal across the Middle East.

G4S said in a statement it agreed that migrant workers deserved to be treated with dignity and respect, and said it had hired a migrant worker coordinator to address the issues raised by the council.
