Retail giant Sports Direct has been compared to a "Victorian workhouse" by MPs as they hit out at the firm's appalling working conditions.

Founder Mike Ashley was bluntly told he was accountable for the "disturbing" treatment of staff, some of whom were promised preferential treatment in return for sexual favours.

Employees at the retailers stores and warehouse in Shirebrook, Derbyshire, were also paid below the minimum wage and penalised for taking even a short break for a drink of water and for taking time off ill.

In a hard hitting report, the Business Committee said its inquiry into the company revealed workers were treated as "commodities" rather than human beings.

The MPs said evidence presented by employment agencies the Best Connection and Transline, which employ staff for Sports Direct, was "woefully poor" and in some cases incorrect.

The committee said it was "deliberately mislead" by Transline and urged the company to clarify some of its evidence.

The committee's report said a spotlight had been shone on the working practices of Sports Direct, which was "extremely disturbing".

"Workers at Sports Direct were not being paid the national minimum wage, and were being penalised for matters such as taking a short break to drink water and for taking time off work when ill," it stated.

"Some say they were promised permanent contracts in exchange for sexual favours.

"Serious health and safety breaches also seem to have occurred.

"For this to occur in the UK in 2016 is a serious indictment of the management at Sports Direct."

Committee chairman Iain Wright (Labour, Hartlepool), said: "The evidence we heard points to a business whose working practices are closer to that of a Victorian workhouse than that of a modern, reputable High Street retailer.

"For this to occur in the UK in 2016 is a serious indictment of the management at Sports Direct and Mike Ashley, as the face of Sports Direct, must be held accountable for these failings.

"It's seems incredible that Mike Ashley, who visits the Shirebrook warehouse at least once a week, was unaware of these appalling practices.

"This suggests Mr Ashley was turning a blind eye to conditions at Sports Direct in the interests of maximising profits or that there are serious corporate governance failings which left him out of the loop in spite of all the evidence.

"This model has proved successful for Mr Ashley and there is a risk this will become much more the norm in Britain.

"A modern and developed economy focused on innovation and supporting entrepreneurialism and enterprise cannot be allowed to operate like this.

"We were also disgusted at the poor evidence given by the agency companies, who deduct money from low-paid workers without proper explanation and justification."

Mr Wright added that he welcomed moves by Mr Ashley to engage with the Unite union, adding he was determined to continue checking on progress made in improving conditions for the workers.

The MPs said it was "irresponsible, if not reckless", for Sports Direct to give the two employment agencies £50 million when they did not seem to have a basic understanding of employment law.

The MPs said they would visit Shirebrook, called for a review of health and safety in the warehouse, and said the Gangmaster and Labour Abuse Authority should look into employment practices.

A spokesman for Sports Direct said: "We will study the contents of the committee's report very carefully. It is our policy to treat all our people with dignity and respect.

"We are pleased to see that the committee has recognised Mike Ashley's commitment to engage in addressing any shortcomings in the working practises at Sports Direct."
