ASOS has hit back at Labour MP Owen Smith over claims that it mistreats its employees.

The ex-shadow work and pensions secretary has accused the fashion giant of “appalling” working conditions and having “the worst forms of zero-hours arrangements” he had ever come across.

ASOS has strongly denied the allegations – stating that Smith had never visited the premises.

In a statement to Vogue, an ASOS spokesperson said: “We were surprised to see these allegations from Owen given that it was the first we had heard from him and he’s never been inside the warehouse,” they said.

“We work incredibly hard with XPO (the logistics company that manages the site) to create a positive, supportive, healthy working environment for the team in Barnsley.

“As we have now said on the record several times before – we don’t do zero-hours contracts, people can take toilet and water breaks whenever they want, and we pay above minimum wage.”

Smith, who is opposing Jeremy Corbyn in the contest for leadership of the Labour Party, made the claims in a letter to fellow politician Ian Wright – chairman of the Business, Innovation and Skills Select Committee – likening the online fashion retailer to sportswear company Sports Direct, which was recently investigated for poor working conditions.

He has also called for a parliamentary investigation over staff conditions at the ASOS warehouse in Barnsley, Yorkshire.

The allegations came after ASOS was named the UK’s most reputable fashion retailer by UK RepTrak.
