File on 4 Investigates

File on 4 Investigates how Immigration Enforcement officers are tackling sham marriages. Claire Jones follows Home Office officials as they apprehend people entering into, and organising fake marriages in order to circumvent the UK’s immigration laws. She discovers details of criminal gangs charging people up to £30,000 for a partner and 'marriage pack', a set of photos and documents designed to create a convincing back story of the fake relationship. After File on 4 Investigates asked the Home Office why more statistics are not available on suspected fake marriages, they have now committed to regularly publishing these numbers 'in due course'.

When a woman reported an allegation of rape against a serving police officer, she found herself in the dock, charged with perverting the course of justice. File on 4 Investigates hears how she went from being a potential victim to a suspect accused of lying. Over the past decade, hundreds of rape complainants in England and Wales have been investigated for making false allegations. The programme examines when and why the justice system turns on those who come forward, and asks whether the safeguards meant to protect potential victims are being properly applied.Producer: Hayley Mortimer Presenter: Rebecca Woods Technical Producer: Richard Hannaford Production Co-ordinator: Tim Fernley Editor: Tara McDermottDetails of organisations offering help and support for the issues raised are available at bbc.co.uk/actionline

File on 4 Investigates reveals new data showing a significant rise in housing disrepair claims, now a growing market for unscrupulous No Win No Fee lawyers. Adrian Goldberg asks, has the Solicitors Regulation Authority learned its lessons from the collapse of the law firm SSB which left hundreds of householders with huge legal bills, and are they able to protect vulnerable social housing tenants from potentially risky NWNF claims? File on 4 Investigates have been told by 5 major housing providers across England and Wales that housing disrepair claims have been growing significantly. One social housing provider in the South of England with an estate of 85,000 homes has told us its seen a 375% rise in the number of legal claims launched by tenants in the last 5 years. We speak to John Golding, a 74 year old pensioner living in a housing association flat in Staffordshire about how a canvasser knocking on his door tried to pressurise him into pursuing a housing disrepair claim with a Manchester based No Win No Fee solicitors' firm.Reporter: Adrian Goldberg Producer: Jim Booth Additional research: Laura Longworth Technical Producers: Richard Hannaford & Cameron Ward Production Coordinator: Tim Fernley Editor: Tara McDermott

Industrial firefighting foams are an essential part of on-site safety in UK factories. But for decades some of these familiar canisters contained potentially dangerous, toxic chemicals. File on 4 Investigates discovers that 3M the multi-billion dollar chemical company responsible for producing the chemicals knew about the risks as early as the 1960s because their own internal studies on animals and tests on workers indicated a possible increase in rates of cancer. Despite this, the company failed to warn its workers of the dangers associated with using the foams for decades and was involved in an environmental accident at one of its sites that led to the chemicals being released into a Welsh river.The programme obtained never seen before documents showing the regulator warning the company it thought it had committed an offence but choosing not to prosecute it.In 2004, with evidence of the risks to the environment of the two specific forever chemicals PFOS and PFOA, a report commissioned by the government recommended any remaining firefighting foams containing the chemicals be incinerated. But we discover in the years after that companies struggled to dispose of legacy stock of foams, and, appearing unaware of the unofficial advice, discharged them straight into the sewer with no treatment, in one case with permission from the water company.3M said that the health and safety of its workers and their families were “critical priorities" for the company.Reporter: Esme Stallard Producer: Anna Meisel Technical Producer: Richard Hannaford Production Coordinator: Tim Fernley Editor: Tara McDermott

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.
