Measures that would have blocked companies found to have used forced labour in any part of the state-owned Great British Energy supply chain from receiving public money could be overturned this week.

Labour MPs are being whipped on Tuesday to throw out the clause that was inserted into the energy bill in the House of Lords in February. But the Labour MP Alex Sobel is proposing to buttress the measure by moving an amendment to the bill that would authorise the independent anti-slavery commissioner to determine whether the threshold of credible evidence has been met.
