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."
Tesco said it had recruited 350 local people to work in its distribution centre in Dagenham, which is in the east London Borough of Barking and Dagenham and was formerly in Essex, not Kent.
It is wrong to accuse Tesco of this. We work incredibly hard to recruit from the local area, and have just recruited 350 local people to work in our Dagenham site.
Tesco has denied having a distribution centre in the county and it is understood the firm will write to Labour to complain about the "unfair" attack.
The biggest complaint I have heard, from migrants and settled communities alike, is about the negative effects migration can have on the UK labour market. And I agree.
It is unfair that unscrupulous employers whose only interest seems to be finding labour as cheaply as possible will recruit workers in large numbers in low-wage countries in the EU, bring them to the UK, charge the costs of their travel and their substandard accommodation against their wages and still not even meet the national minimum wage.
According to extracts of tomorrow's speech reported in The Sunday Telegraph, Labour minister Chris Bryant will acknowledge that immigration can have a negative effect on labour markets.
Labour's Shadow immigration minister has clashed with supermarket giant Tesco over claims made by a senior MP about recruiting foreign workers.
Chris Bryant is set to highlight the activities of Tesco in a speech attacking "unscrupulous employers" who recruit cheap labour from Eastern Europe.
In a speech tomorrow, he will claim the supermarket moved its distribution centre to Kent where a "large percentage" of the staff are from the eastern bloc, the Sunday Telegraph reported.
