File on 4 Investigates

The way in which oil is traded on commodities markets is coming under close scrutiny. Last month, officers of the European Commission raided the London offices of BP and Shell along with Norway's Statoil company and the leading price reporting agency Platts. They said they were investigating claims of collusion to manipulate the prices of oil and biofuels on the international markets.

A leading city insider tells File On 4 that the price-reporting mechanism for oil is 'wide open to abuse'

So are petrol prices being kept artificially high by hidden forces beyond the normal workings of supply and demand ?

Gerry Northam investigates and asks whether British regulators are proving slow to recognise the potential problem.

Local authorities across the UK are facing tough decisions as they try to balance their books in the face of unprecedented funding cuts - with many opting to sell land and buildings to reduce spending and bring in much needed capital.

But, one person's white elephant is another's much loved local facility, so the choice of what goes on the market often causes great public resentment.

Jenny Chryss visits four local authorities where announcements about asset sales have caused serious questions to be asked. She finds allegations of decisions taken behind closed doors, sums that don't stack up and property that could end up being mothballed for years to come.

So are councils getting value for money for their tax payers? Or are they out of their depth when they negotiate with the private sector, especially in one of the harshest property markets for years?

And with a major shift in the way councils are audited, is there a danger that mistakes could go unnoticed and unchallenged?

In the latest high profile grooming trial, 7 men from Oxford will be sentenced later this month for sexually exploiting and raping 6 schoolgirls. Police said the girls - some as young as 12 - were 'abused to the point of torture' for years. One girl was injected with heroin. Another was forced to have a backstreet abortion.

The police praised the young women for finding the strength to give evidence against the gang and protect other girls.

But, after the legal process ends, what support is there for victims?

After a string of such abuse cases around the country, Jane Deith finds there are many young women who say they've been let down by the authorities and are struggling, alone, with mental health problems and difficulties with education and housing.

More victims of grooming are being rescued. But does being sexually exploited as a child mean a life sentence?

Operation Jasmine was the UK's biggest ever care home abuse investigation.

But in January this year proceedings against two key figures in the case collapsed, leaving dozens of families asking if they will ever get justice.

While relatives demand a public inquiry into what happened in the six Welsh care homes at the centre of the case, 12.5 metric tonnes of unpublished evidence lie in a Pontypool warehouse.

Experts say prosecutors too often face insurmountable difficulties in bringing people accused of neglecting the vulnerable to justice. Several high-profile figures are now calling for a change in the law: one barrister and academic tells File on 4 current legislation gives greater protection against cruelty to animals than against people.

With other major scandals such as those at Winterbourne View and Mid-Staffordshire still fresh in the public mind, Fran Abrams asks if the justice system is fit for purpose when it comes to dealing with abuse and neglect.

There's mounting concern over the Iranian nuclear programme. Is Tehran is simply playing cat and mouse with the international community and buying time until it is ready to develop a nuclear weapon? Evidence is emerging that Iran is co-operating with North Korea, a country which has already developed its own weapon.

The latest report from the UN's international watchdog, the IAEA, is due out next month - but has the IAEA been strong enough in its dealings with Tehran and Pyongyang?

Reporter Rob Broomby charts the history of concealment of Iran's nuclear activities and its refusal to abandon the most controversial parts of its programme, despite numerous UN Security Council resolutions and a raft of sanctions. In a detailed interview with File on 4, Iran's ambassador dealing with nuclear matters, Ali Ashgar Soltanieh, denies his country is a "serial offender". But can protestations of innocence be taken seriously when Iran still refuses inspectors access to key sites and documents?

The programme also examines the role of the IAEA in dealing with Iran and hears from former nuclear inspectors, ex-Whitehouse officials, diplomats and experts. Is the Agency up to the job of preventing states from acquiring the bomb?

In the first of a new series, File on 4 asks whether recent stark warnings about the threat posed by growing resistance to antibiotics have come too late.

The high profile child sex abuse case in Rochdale last summer - in which nine men were jailed for more than 70 years for grooming underage girls - has been defined as a watershed moment in how the authorities deal with this kind of abuse.

In the wake of the Mid-Staffordshire hospital scandal, investigations are going on at 14 other hospitals in England identified as having above average death rates among their patients. But why has it taken so long for enquiries to begin? Should the Department of Health and the hospitals regulator, the Care Quality Commission, have sounded the alarm much earlier?

It took a lengthy public inquiry to get to the bottom of failings in Mid-Staffordshire. Complaints of dangerous clinical practice and shoddy nursing standards were overlooked while whistle-blowers were treated as mere troublemakers and threatened with reprisals if they went public with their concerns.

Evidence is now emerging of a similar pattern in other places.

Gerry Northam examines the list of hospitals now under investigation and hears from doctors, nurses, patients and bereaved relatives. Have NHS managers done enough to address concern about high death rates?

How could it happen that the hospital reported to have the highest rate of excess mortality in the country - 20% above the expected level for its population of patients - was given a full seal of approval only three months earlier by the official regulator?

The French authorities acknowledge their intervention in Mali has made them terrorist target number one. In recent weeks, the country has raised its threat level - with high visibility police patrols at tourist destinations and government buildings - and a number of people suspected of planning to join Islamic extremists in Mali have been arrested.

Jenny Cuffe examines concerns in France both about the rise of Islamist extremism and the tough action the authorities are taking in response. Last October, police uncovered bomb making equipment following a grenade attack on a Jewish butchers in Paris. Eight months earlier, extremist Mohamed Merah killed three soldiers and a rabbi and three children outside a Jewish school in Toulouse. Meanwhile more than 100 imams deemed to be dangerous have been deported in the last ten years and several more are currently under threat of being expelled.

The programme also examines the threat to the UK. Jihadist groups in North Africa have warned that they will target supporters of the French action in Mali. The British Government is currently seeking to deport a number of Algerian terror suspects and authorities are also investigating reports that a British man has been arrested trying to make his way to join jihadists fighting in Mali.

Has the Government done enough to protect communities from flooding? Were cuts in river maintenance work responsible for farmers land in Somerset being underwater for months? Why are planners allowing developers to continue to build on floodplains? A committee of MPs accuses the Coalition of being woefully slow to bring in measures to combat the problem. Allan Urry investigates.
