PRIMARK is recalling thousands of men’s flip-flops over fears they contain a cancer-causing chemical.

The low-cost fashion chain said the affected footwear, part of its Cedar Wood State range, "does not meet the Primark usual high standards for chemical compliance".

On the website it said: "We have found levels of a restricted substance in the product in excess of the 1.0 mg/kg requirement."

The recalled flip-flops are in blue, black and khaki.

The chemical, chrysene, is used in dark coloured dyes and is noted to pose a carcinogenic risk.

A spokesperson for Primark, which is offering a full refund, said: "We take the safety of our customers, and the quality of our products, very seriously, which is why we have chosen to recall three men’s flip flops from our Cedar Wood State range.

"All new orders with this factory have been suspended while we carry out a thorough investigation."
