Labour has backed down on claims that Tesco and Next are examples of "unscrupulous employers" over their use of foreign workers. The party became embroiled in a row after the shadow immigration minister...briefed newspapers that he would criticise both firms for favouring foreign workers over Britons. But just hours before he was due to give a keynote speech on the issue,...[he] was forced to retreat from his case as Tesco and Next accused him of making basic errors. The senior Labour MP insisted he had meant more generally that "sometimes there are negative sides of migration in terms of the labour market".
