File on 4 Investigates

Flights grounded. Trains cancelled. Roads flooded. It's becoming a familiar story every winter as Britain's transport systems are battered by the weather. While rainfall this winter has been unusually high, has some of the disruption that we've seen been caused by a lack of strategic planning and routine maintenance? Should a flooded river have been able to knock out power supplies at Gatwick, catching airport authorities by surprise? Were the drainage systems adequate on some of the railway embankments that collapsed, leaving passengers stranded? Allan Urry investigates why our infrastructure is struggling to cope with the storms and asks whether bad planning has made a bad situation worse?

Ministers have promised a new focus on home care for the elderly and disabled amid concern that 15-minute calls and a low-paid, underskilled workforce are leaving vulnerable people at risk.

From this Spring, inspectors will ask how councils' commissioning practices are affecting the daily lives of those they care for. But with authorities under pressure simultaneously to cut costs, will quality continue to suffer?

Fears have been mounting about whether the basic needs of vulnerable people are being met. The government's human rights watchdog has been pressing the issue, along with tax officials who say many companies are breaching minimum wage legislation.

This week File on 4 reports on the results of its own survey of local authorities in England. Have councils increased spending to keep pace with inflation in the past few years, or have they actually driven down costs? And are they providing even the most basic level of resources that social service chiefs say are needed to keep those in their care safe and well?

A year after the horsemeat scandal there are calls for a new police force to fight food fraud amid concerns that organised crime is increasingly targeting the sector because there are huge profits to be made at the expense of the consumer.

Last month a report by a government advisor, Lawrence Tomlinson, accused The Royal Bank of Scotland of forcing some viable businesses into insolvency. The Bank has denied Tomlinson's claims and has asked a leading law firm to carry out an independent investigation. With their findings due to be published shortly, File on 4 assesses the evidence.

Jane Deith speaks to families who claim their companies were unfairly forced to the wall and their lives ruined as a result of the actions of the Bank's Global Restructuring Group.

Billed as the equivalent of an intensive care unit designed to help nurse distressed businesses back to health, did the Global Restructuring Group kill some of them off instead? And was RBS able to profit as a result?

With a rising tide of complaints against the taxpayer-owned bank, the Financial Conduct Authority is beginning its own investigation.

So, was RBS being predatory or prudent?

As water companies submit their spending plans for the next five years, Lesley Curwen investigates what happens to the money once the household water bill has been paid.

Half of England's water companies are now in the ownership of global investment funds. In many cases these corporate bodies are run and financed from abroad behind closed doors. They use a web of companies some in off-shore tax havens to provide a steady flow of dividends to their shareholders.

But is their mechanism for generating shareholder income at the expense of the customers who are looking for lower bills and sustained investment in their water supply?

As a complex operation continues to destroy the remainder of Syria's chemical weapons stockpile, how much will we ever know about the supply routes through which the Assad regime acquired the basic ingredients for its arsenal? Vast quantities of chemicals are traded around the world every day, so what chance do we have of controlling their use by rogue states and terrorists? In the first of a new series, Allan Urry reports from the headquarters of the OPCW - the organisation set up to stop the spread of chemical warfare and which is overseeing the removal and destruction of the Syrian weapons. He also investigates the efforts of terrorist groups including Al Qaeda and al Shabab to develop nerve agents of their own; and examines the global attempts to limit the availability of "dual use" chemicals which are essential in the manufacture of every day products from fertilisers to toothpaste but which can also be turned into powerful explosives for use in IEDs and other bombs.

The biggest ever slice of the NHS is up for grabs in Cambridgeshire. Ten bidders, including NHS hospital trusts and private companies Serco, Virgin Care and Circle, are competing for a five year contract to run older peoples' services. It will be worth a minimum of £700,000. The successful bidder will provide everything from podiatry and occupational therapy to dementia treatment and end of life care. The stakes are high. But how much will patients be told about how the bid was won? With commissioners advertising dozens of other big money tenders, File on 4 looks at the secrecy surrounding NHS contracts when they're awarded and when they're challenged. Does commercial confidentiality make public accountability impossible? And how far does the competitive market improve healthcare for patients?

The Work Programme is the Government's flagship scheme designed to help the long term unemployed off benefits and into lasting jobs. But how well is it working - both for those at whom it is aimed and for the private companies who are paid to deliver it?

What's behind the recent death of a clubgoer in Manchester who's believed to have taken a bad dose of the drug ecstasy? He's one of 12 in the area in the last year who've died after using illegal stimulants with toxic new additives, prompting the Government's Chief Medical Officer to issue a formal alert. Police are concerned organised crime is hiring backstreet chemists to cook up their own toxic amphetamines. Allan Urry investigates.

Ministers have set a target of 170,000 new affordable homes in the next two years. But the Housing Associations which must take a major part in delivering them are under increasing financial strain.
