File on 4 Investigates

The Dutch city of Nijmegen has much in common with the English city of York. Similar in size, both are much visited by tourists because of their histories and architecture. But both also have rivers running through them and are susceptible to flooding. So how do their defences compare? And, as York and other communities continue to mop up the damage caused by the latest catastrophic flooding, did basic mistakes and a failure of planning make a bad situation very much worse?

Vaccination has long been one of the greatest weapons in the battle against a range of potentially fatal diseases. Millions of lives have been saved worldwide, and Britain has played a major role in helping to combat new pandemics. But, rarely, things do go wrong and people develop serious side-effects. In the UK, the Government's Vaccine Damage Payment Scheme is supposed to help those left severely disabled as a result. Among those currently arguing their case are the families of children who developed an incurable and devastating sleep disorder after being immunised against swine flu. But, to date, most have received nothing and Ministers have now gone to the Court of Appeal to try and establish a less generous interpretation of the pay-out rules. Lawyers for the families say the whole scheme is outdated and unfit for purpose. Are they right? Jenny Chryss investigates.

File on 4 uncovers the story behind the collapse of one of the biggest health contracts ever put out to tender. Last April an NHS consortium of Cambridge University Hospitals and Cambridgeshire and Peterborough NHS Foundation Trust successfully bid to run older peoples' health services. But in December the £800m, five year contract ended without warning, with local commissioners saying only that it was "no longer financially sustainable." Jane Deith asks what the failure of the Cambridgeshire contract means for the broader policy of trying to improve NHS services by opening massive contracts to competition between Trusts and the private sector.

File on 4 reveals secret evidence of match fixing in tennis and investigates claims that sport's governing bodies have failed to act on repeated warnings about suspect players. The programme has seen confidential documents which reveal how some were linked to gambling syndicates in Russia and Italy which won hundreds of thousands of pounds betting on matches they played in. A number of those who have been repeatedly flagged on fixing lists passed to the game's Tennis Integrity Unit have continued to attract highly suspicious gambling activity. Reporter Simon Cox also has an exclusive interview with one of the most high profile players to be banned for match fixing who says the problem is widespread in the sport.

In the first of a new series, Allan Urry investigates claims by former officers from one of Britain's biggest police forces that they've been the victims of crimes committed by their own colleagues. He hears claims of dirty tricks by a secretive police unit within Greater Manchester Police which some officers say have led to criminal charges against them. Others say they've been unfairly targeted through the internal disciplinary process, with evidence distorted and statements changed.

Are they bad cops with an axe to grind or victims of corrupt practices and institutional cover up?

An inside job: the Britons smuggling illegal immigrants into the UK.

How safe are we in the hands of locum staff at NHS hospitals? The Government's crackdown on big fees charged by agencies that hire them out has been making headlines, but what's being done to ensure they are up to the job?

As the crisis in Syria deepens and refugees flock westwards, the UK government insists it is helping with a £1.1bn aid package to neighbouring countries - but is it being spent wisely?

Simon Cox tracks money going from the UK to projects on the ground in Syria, Jordan, Lebanon and Turkey, trying to find out how much eventually gets to refugees. It's easy to see how funding an NGO to build new homes for Syrians is money well spent. But can the same be said for the hundreds of millions of pounds that go through the United Nations?

The programme hears from aid workers, UN officials, refugees and UN investigators about cuts to food rations against a backdrop of high salaries and overheads.

So is the UN up to the job of managing a modern-day refugee crisis?

Like other steel communities, Rotherham faces the loss of hundreds of jobs following the recent announcement of redundancies at the local plant. It's the latest blow to a town now synonymous with widespread child grooming. Last year the Jay Report estimated that 1400 young people had been sexually abused there. It said most of the victims were white and most of the perpetrators were Asian men. So what's been the impact on community relations and how far has the scandal affected the local economy? For File on 4, Manveen Rana returns to the town to talk to families, business owners and the authorities to find out whether Rotherham can recover.
