Next have come under fire for their reliance on Polish labour from shadow immigration minister Chris Bryant.
In a wide-ranging speech later today, the Labour MP will attack the fashion and homewares store for their use of temporary Polish migrants.
Mr Bryant is expected to say: "Look at Next Plc, who last year brought 500 Polish workers to work in their South Elmsall warehouse for their summer sale and another 300 this summer. They were recruited in Poland and charged £50 to find them accommodation.
"The advantage to Next? They get to avoid Agency Workers Regulations, which apply after a candidate has been employed for over 12 weeks, so Polish temps end up considerably cheaper than the local workforce, which includes many former Next employees."
