'Government ministers froze funding to a charity led by David Miliband after it silenced 37 sex abuse, fraud and bribery allegations, it has been claimed.
The International Rescue Committee, which is headed by the former Labour foreign secretary, was given millions in taxpayers' cash before the allegations were made.
A team from the IRC was sent to probe claims of wrongdoing in the Democratic Republic of Congo.
Yet a leaked report from the Department of International Development (Dfid) shows the funding to the charity was cut after 'direct reporting of sexual harassment and fraud'.
A Dfid spokesman told The Sun: 'DFID became aware of serious allegations relating to this programme in August 2016.
'The Department acted swiftly to ensure the reported misconduct was fully and comprehensively addressed by the IRC and relevant authorities.'
Mr Miliband left politics and joined the IRC in 2013 shortly after losing the Labour leadership election to his brother Ed. He remains in the post today.
He is mentioned by name in the report, although there is no suggestion he is involved in any alleged wrongdoing.
Although it is not established when any alleged wrongdoing occurred, Dfid was made aware of the claims in 2016, during Mr Miliband's tenure at the IRC.'
