File on 4 Investigates Folgen

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?Producer: Ian Muir-Cochrane.

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.

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?Reporter Jane Deith Producer Ian Muir-Cochrane.
