Campaigners funding Nigel Farage are selling £20 Leave.EU T-shirts made by workers in Bangladesh paid just 39p an hour.
The T-shirts are sold by the Leave.EU campaign, which boasts it is “backing Britain” and wants more jobs here.
Leave.EU is bankrolled by controversial tycoon Aaron Banks, who donated £450,000 to Mr Farage after his Euro election triumph with the Brexit Party.
That victory came ten years after he promised “British jobs for British people” while campaigning for departure from the European Union.
Last night Labour MP Virendra Sharma said: “These people don’t give a damn about British jobs – they just care about pursuing their ideological dream of a hard Brexit.
“Unfortunately for them, the British public do care about this country’s prosperity.”
The MP, who backs the Better for Britain campaign, said: “That’s why a growing majority of the public now want a final say on Brexit with the option to stay in the EU.”
A recent Parliamentary report said that textile workers in Leicester are paid less than the UK minimum wage as factories break the law to compete with dirt-cheap imports.
Meanwhile, the UK experienced its largest contraction in three years as car plants shut down and production dropped 24 per cent amid Brexit fears.
Canadian T-shirt firm Gildan, whose label is on the Leave.EU T-shirts, has them made at a factory in Dhaka, the capital of Bangladesh.
Anti-poverty campaigners say its employees, who live in shanty towns nearby, are paid well below a living wage. A junior machine operator earns around the local minimum wage of £73.85 a month for a 48-hour a week (39p an hour), far less than the £149 campaigners say is needed to live comfortably.
Clothing production in Bangladesh is often criticised by human rights groups. In 2013, 1,130 people, mostly garment workers, were killed when the Rana Plaza factory collapsed.
Mr Farage campaigned alongside Leave.EU in the run-up to the 2016 EU referendum, when Mr Banks was a major backer. Mr Farage stepped down as UKIP leader later that year, but remained an MEP before launching the Brexit Party in March this year. Leave.EU founder Mr Banks gave Mr Farage £450,000 to cover his living expenses in the year that followed.
This was not declared to the EU and this month the European Parliament called a hearing into the donation.
Mr Farage refused to attend, saying he did not need to declare it because at the time he was about to leave politics and start a new life in America. He insisted he had not received “any private money for political purposes”.
Mr Banks said he had “willingly helped Farage and was honoured to do so”, adding: “This was all designed to help Nigel get out of politics.”
Asked about having campaign T-shirts made in Bangladesh, Leave.EU spokesman Andy Wigmore responded: “So what?” He added: We are internationalists, not little Europeans, and we love to support Commonwealth countries.”
Yesterday a Gildan spokesman said that since 2010 the firm had spent nearly £20million improving its Dhaka factory, which employs 3,500 people. Only trainees got the lowest wage, which was slightly above the industry minimum, and everyone got “incremental benefits”.
