File on 4 Investigates

Business travel and Christmas holidays were ruined for hundreds of thousands of people by snow. While many airports abroad bounced back quickly from bad weather, some in Britain began to resemble refugee camps. But discontent among passengers and airlines goes well beyond winter readiness.

Each year, around 250 parents and carers are accused of killing or injuring children by shaking them or inflicting some other form of head injury. But an acrimonious scientific debate over the theory behind so-called Shaken Baby Syndrome, has turned toxic among the expert witnesses whose evidence is so critical in determining guilt or innocence.

Are police doing enough to tackle corruption in their ranks? Following a number of high profile trials in which officers have been jailed, Allan Urry investigates the crimes they committed and asks if more could have been done to stop them. A constable given a life sentence earlier this month for a series of sex attacks on vulnerable women he met while on duty, had previously been put on trial for rape, during his time in the army. Why didn't the police service know this when they agreed to employ him?

Reporter Jenny Cuffe investigates claims that one of the groups behind the blasphemy law in Pakistan is also active in the UK. The religious extremists are accused of spreading a hate message against members of other Islamic sects who they regard as infidels. One group that's been targeted accuses the authorities of not doing enough to protect them - and says political correctness has resulted in Britain tolerating the intolerant.

Homes but no loans. Despite the threat of a new slide in house prices and rising levels of negative equity, the number of property-buyers having their homes repossessed has declined over the past year. But now many economists predict interest rates will rise in the course of 2011, fuelling fears that Britain's housing market could be facing a double dip. With banks chasing profits and affordable mortgages harder to find. Michael Robinson asks what impact the new housing freeze will have on Britain's already battered economy.

Legal aid has been withdrawn from a long-running case against a pharmaceutical giant. Children born with severe disabilities, including spina bifida, were suing the manufacturer of an anti-epilepsy drug which their mothers took during pregnancy and which they blame for causing birth defects - a claim the company denies.

After years of legal proceedings which the claimants' solicitors say have so far cost £3.25m, the Legal Services Commision refused a much smaller sum to take the case to trial, just weeks before hearings were due to start. As a result, more than a hundred claimants are left with no chance of their day in court.

Their case was not deemed strong enough to pass the standard test which requires them to prove that the drug doubled (at least) the risk of harm. This test is called into question by experts in cases against pharmaceutical companies in Britain and the USA. A lower level of proof is needed in American courts.

The government has announced that future patients in England and Wales alleging clinical negligence or personal injury can expect to have their applications for legal aid refused under its programme of spending cuts.

No such change of policy is planned in Scotland. A case is proceeding there with support from legal aid by a patient who took another drug, for relieving arthritis, which is blamed for increasing the risk of heart attacks and strokes - again this is denied by the company concerned. Patients in England and Wales who took the same drug and suffered heart attacks have been turned down for legal aid funding and have shelved their cases.

Will government cuts effectively put wealthy pharmaceutical companies beyond challenge in the civil courts?

Europe's Missing Millions

Over the last seven years, the European Union has paid out billions of Euros in grants designed to revitalise Europe's poorest regions.

But an investigation for File on 4 has revealed the extent to which these payments are open to widespread fraud, abuse and mismanagement.

Angus Stickler tracks how money has gone astray across the 27 member states and asks why funding continues in regions with proven records of corruption and fraud. Throughout the EU there is evidence that money has been wasted or even stolen. In Southern Italy, money has gone to Mafia-controlled construction companies and bogus energy projects. Across the EU expensive projects lie unused and unfit for purpose, despite receiving funding of millions of Euros.

The EU has created its own anti-fraud agency, OLAF, to stop these abuses, but are critics right when they claim it's underfunded and ineffective?

A new law regulating care homes in England came into force last month. All homes must be registered and ensure they meet certain standards of quality and safety. The regulator - the Care Quality Commission - is promising to monitor homes and take action against those who fail to meet standards.
