An unholy row over bishop accused of bullying.

Anne Dyer is a trailblazer - becoming the first female Bishop in the Scottish Episcopal Church when she was appointed more than seven years ago. But since then, accusations of bullying and misconduct have dominated her period in charge - even for a time leading to her suspension and calls for her resignation. Bishop Dyer denies any wrongdoing, while the church itself acknowledges there are deep wounds within the diocese of Aberdeen and Orkney. Now File on 4 Investigates has discovered new complaints against the bishop, which she says are "totally without merit".Reporter: Steve Swann Producer: Fergus Hewison Editor: Tara McDermott Production Coordinator: Tim Fernley Technical Producer: Richard Hannaford

File on 4 Investigates discovers a world of lies and blame within adoption in the UK. The BBC has conducted the most extensive Freedom of Information request ever into adoptions that have broken down, finding that more than 1,000 adopted children in the UK have returned to care in the past five years. That is much higher than the figure in a recent government report - but the true number is likely to be even larger, as only a third of authorities said they collected this data as standard practice. Some adoptive parents say they’ve been given so little support that they’ve been forced to return their children to the care system. This programme explores the scale of the crisis as we hear from parents pushed to the limit, a teenager returned to care and a social worker giving a rare view of the system from the inside.Producer: Ashley Kennedy & Claire Kendall Reporter: Judith Moritz Sound designer: Richard Hannaford Production coordinator: Hattie Valentine Editor: Tara McDermott(Photo: Close-up portrait of couple Verity & Ian standing outdoors.

Multi cancer detection tests or MCDs can detect many cancers through a simple blood test. Many detect fragments of cancerous DNA that have broken off a tumour and are circulating in the blood. They can often then identify where the cancer may be. The NHS is currently involved in the words largest trial of one such test. The Galleri test is made by US firm Grail and the company says its mission is to detect cancer early when it can be cured. Heavyweight investors include Jeff Bezos and Bill Gates.More than 140,000 volunteers took part in the trial and the results will be known next year. If successful, the test may be rolled out further. File on 4 Investigates looks at how effective such tests are and whether the trial will show it can save lives.Medical journalist Deb Cohen speaks to one woman whose cancer was found by the test and successfully treated. But she also hears from firefighters in America - where it's available to the public - who say it missed some cancers and some people who got a positive result were found not to have the disease after undergoing diagnostic procedures - a so called false positive.With many hospitals trusts missing cancer treatment targets, what is the best way forward for the NHS to improve outcomes.Reporter: Deb Cohen Producer: Paul Grant Technical producer: Craig Boardman Production co-ordinator: Tim Fernley Editor: Tara McDermott

An ambitious plan to digitalize the courts was meant to remove the need for hundreds of thousands of paper documents. But File on 4 Investigates has discovered an IT system, introduced as part of a £1bn project, has been plagued with technical faults - causing crucial information to go missing, be overwritten, or appear lost. The government body that runs the courts in England and Wales has now checked hundreds of thousands of benefit and child support appeals to identify if any were affected by missing evidence. But sources say the IT bug was known about for years before action was taken.Original journalism by Alys Harte. Reporter: Datshiane Navanayagam. Producers: Lorna Acquah, Fergus Hewison.

A van selling coffee and sandwiches from an office car park doesn’t sound like anything special, but there’s one in Swindon helping to keep young offenders out of custody. It’s part of an approach being deployed across the country trying to prevent young people from reoffending by encouraging a shift in their identity. The idea is to get to know the young offender, figure out what makes them tick. And then, instead of locking them up, find ways of getting them involved in whatever interests them. Selling tea and coffee from the burger van is where those with a culinary eye can learn new skills and start to feel valued for being part of legitimate endeavours. Similar interventions include social enterprises working in bicycle maintenance, hair and beauty and podcasting. As the adult prison population has soared in England and Wales, the number of under-18s behind bars has dropped markedly in the past 20 years, from around 3000 to 400. File on 4 Investigates spends time with the Youth Justice Service in Swindon to find out how it rehabilitates young offenders in the local community, and asks if the success of the youth system could hold lessons to address chronic overcrowding problems in adult prisons. Chris Marston, who presents shows on National Prison Radio and spent 10 months in prison discovers that what’s going on in Swindon is very different from his own experiences of the adult criminal justice system.Reporter: Chris Marston Producer: Beth McLeod Technical Producer: Craig Boardman Production Co-ordinator: Tim Fernley Editor: Nick HollandMain Image: Presenter Chris Marston in front of the Solid Ground coffee van in Swindon.
