File on 4 Investigates Folgen

There are some two million people with long Covid in the UK - and most of them - around one and a half million - have symptoms that interfere with day to day activities. Fatigue, breathlessness, heart palpitations and severe dizziness are just some of the conditions people experience.Currently there’s no test for long covid and it could be years before we know for sure how best to treat the condition. This struggle to get help is leaving some very unwell people desperate - and willing to try anything to get better. There are treatments to wash your blood, high pressure oxygen chambers normally used by deep sea divers. A rainbow of supplements. All with varying degrees of evidence. And perhaps most strongly dividing opinion - programmes that claim to retrain long Covid patients' brains to stop their symptoms. They say they can help people recover from illness by rewiring the brain using techniques to influence physical changes in the body. Rachel Schraer - the BBC's health and disinformation correspondent - hears from people with long Covid who say the programmes didn't work and in some cases made them feel worse. Others say they fully recovered. Reporter: Rachel Schraer Producer: Paul Grant Technical producers: Cameron Ward and Nicky Edwards Production co-ordinator: Tim Fernley Editor: Carl Johnston

Manchester City are dominating English football, with a trophy cabinet full of silverware. The club’s success has been bankrolled by money from Abu Dhabi. Now Newcastle United have followed in their wake, with backing from a Saudi consortium transforming a sleeping giant of English football into perhaps the world’s richest club. But with the money comes accusations that the clubs are being used to launder the reputations of repressive regimes accused of human rights abuses, and that the cash from the two oil rich states is being used to exert political influence locally and nationally in the UK.Reporter: Adrian Goldberg Producer: Fergus Hewison Technical Producer: Craig Boardman Production coordinator: Tim Fernley Editor: Carl Johnston

Three years ago, dozens of memory sticks were discovered in a sealed box at a school for children with special educational needs. There was 500 hours of footage which showed children being held in so-called 'calming rooms.' The videos showed the children being hit and denied access to a toilet. File on 4 investigates why a subsequent police investigation and an independent inquiry didn't lead to staff being sacked. File on 4 reveals how staff who were filmed hitting, kicking, and leaving children sitting in urine have not been sacked or referred to the barring service.Reporter: Noel Titheradge Producer: Annabel Deas Technical Producer: Craig Boardman Production Coordinator: Tim Fernley Editor: Carl Johnston
