A women’s rights group pledged to take fundraising merchandise off the shelves yesterday if allegations that campaigning T-shirts were made in sweatshops are true.

The Fawcett Society promised supporters it was investigating whether its “This is What a Feminist Looks Like” shirts were made by women paid just 62p an hour.

The Mail on Sunday claimed that the garments — recently sported by Labour leader Ed Miliband among others — had been produced by women living 16 to a room in a Mauritian factory.
