BCC and TUC make joint demand over rights of migrants The British Chambers of Commerce (BCC) and the TUC have joined forces to call for Theresa May to immediately guarantee the rights of European Union migrants to remain in the UK, claiming that further uncertainty over the issue will be seriously damaging for the economy. In a letter sent to Downing Street last night, they say that the PM needs to make a bold unilateral move to put the guarantee in place. The government must also “hold to account the small number of unethical employers who exploit migrant workers to undercut pay and conditions of employment,” the letter added.
