File on 4 Investigates Folgen

Recent high-profile collapses of high street names such as Comet, Phones4U and other companies have left thousands of people out of work and have cost the taxpayer millions in statutory redundancy payments and unpaid taxes. This week File on 4 goes behind the headlines to examine the role of the companies' private equity backers. Were these failed businesses which were bound to have to close? Or might they have survived for longer under different ownership? Fran Abrams investigates. Producer: Emma Forde.

As inquiries into child abuse in Rotherham continue, File on 4 investigates claims of a hidden problem of sexual abuse within Britain's Asian communities.While the victims of recent grooming scandals have mostly been white girls, campaigners say Asian boys and girls have also been subjected to abuse over many years.Male and female survivors tell Manveen Rana there's a powerful culture of denial stopping many speaking out and getting justice.

Ebola is now regarded as an international threat to peace and security, according to the World Health Organisation. Yet, when the WHO was first warned of an unprecedented outbreak, the organisation said it was "still relatively small." Now the UK has asked for volunteers to travel to West Africa to try to bring Ebola under control. Thousands of American troops are also flying out to the region. But could all this have been avoided? Simon Cox asks why it took so long for the world to wake up to the threat posed by Ebola? He also investigates the treatments that are now, belatedly, being developed - treatments that have existed for decades. Vaccines and other drugs are being rushed into production at an unprecedented pace, by-passing the usual safety controls. However, all predictions are that many more people will die before the disease is brought under control. Even then, will it become endemic?Reporter: Simon Cox Producer: John Murphy.
