File on 4 Investigates

UK companies are being used to launder dirty money as new transparency rules are flouted. One, registered in a Hertfordshire commuter town, helped the circle of Ukraine's disgraced ex-president profit from last year's Eurovision Song Contest, a File on 4 investigation has found.

Billions of pounds of dirty money is alleged to have passed through opaque UK companies in recent years, over 100 of them registered at the same Potters Bar address. Tim Whewell follows the trail of one company linked to the regime of former Ukrainian president Viktor Yanukovych, who fled the country for Russia four years ago after anti-corruption protests in Kiev's Maidan square.

Can new transparency requirements for British firms help find the people really behind the company?

There were a record 3,744 drug related deaths in England and Wales last year. While many were linked to street drugs such as heroin, a growing number also involve prescription medicines such as benzodiazepines and Fentanyl.

There are more than half a million people living in sheltered housing, accommodation that offers additional support to the elderly, disabled or vulnerable.

But currently, in England, these schemes aren't overseen by the independent regulator of health and social care the Care Quality Commission and councils aren't required to record cases of abuse and neglect in sheltered housing.

It is leading to growing concerns that many vulnerable residents are hidden away and left to suffer without the authorities ever knowing there is a problem.

With a move to care being provided via direct payments, its likely the demand for sheltered accommodation will grow. But there's concern that new developments are being shelved due to ongoing uncertainty over funding.

File on 4 speaks to people who have been taken advantage of while living in sheltered accommodation, who feel they were sitting ducks for people looking to prey on the vulnerable.

And when things do go wrong, with an absence of regulation are there sufficient mechanisms to prevent the same things from happening again?

File on 4 exposes a multi-million pound global trade in fake diplomas.

A complex network of online universities sells degrees, doctorates and professional qualifications - for a price. Some of the buyers have gone on to trade on these credentials, including them on their CVs and gaining jobs in public life.

Others, after making an initial purchase, were blackmailed by the sellers, who threatened to expose them unless they paid out huge additional sums of money.

Despite criminal investigations in numerous countries, why is there still a thriving trade in dubious qualifications and are institutions and companies taking the issue seriously enough?

The head of counter terrorism Assistant Commander Mark Rowley has warned the extreme right wing pose a growing threat in the UK. He told the Home Affairs select committee last month that right wing issues had increased in the last two years which was a real concern, although Islamic extremism remained the main threat.

Last month, two men alleged to be members of National Action - a banned extreme far right group - were charged in connection with an alleged plot to kill an MP.

Adrian Goldberg investigates the current face of the far right in the UK today and hears from their victims.

He meets the former soldier who intervened after a far right extremist tried to behead a Sikh man and challenges the Austrian leader of a group called Generation Identity which launched in the UK only last month.

They are part of a Europe wide group of so called 'Identitarians' who say their aim is to protect cultural identity. But their target is clear. Members unfurled a banner over Westminster bridge in London which declared "Defend London, Stop Islamisation."

Experts say there is now growing cross border co-operation between far right groups in Europe, the UK and America.

Jewish communities are also worried about the rise in the far right and growing anti-Semitic attacks. A student who highlighted far right posters being put up at her university was forced to move after a hate campaign which included her face being superimposed on pictures of holocaust victims. Businesses have been firebombed and some members of the Jewish community say they are so concerned they are considering leaving the country.

The programme reveals new research on the scale of far right extremism on-line. Thousands of people in the UK have been identified as having violent extremist thoughts. Former extremists have been brought in to try to persuade people to change their views. But are they listening?

There a risk we won't get new nuclear hooked up to the grid in time to back up renewable energy like wind power.

There's an aim to generate 16GWe of new nuclear power by 2030.

But experts doubt that's a realistic prospect, with Hinkley Point C years late, and questions over whether investors will risk capital on a proposed plant in Cumbria. And as plans for the future of nuclear power evolve, the legacy of the past also needs to be dealt with.

The government's served notice on a £6billion contract to make safe a dozen of the UK's first nuclear sites, dating back to the 1950s.

It was the most valuable piece of work ever put out to tender by the government.

But the Nuclear Decommissioning Authority gave the job to the wrong consortium. The high court ordered a payout to the rightful winners of £97.3 million in damages.

The government also has to find someone else to clean up the old Magnox power stations and nuclear research sites. The current contractor, Cavendish Fluor Partnership and the NDA agree the job is far bigger than was made clear, and CFP will down tools nine years early.

File on 4 looks at the delays and spiralling costs in decommissioning old power station sites.

So just how well is our nuclear industry being managed?

Drug dealers from big cities are exploiting thousands of teenagers to traffic Class A drugs to smaller rural towns in what's known as County Lines.

Children - some as young as 9 -are being used as runners to move drugs and cash from cities like London and Manchester hundreds of miles away to other areas of the UK.

It's a massive problem which until recently was being ignored.

File on 4 hears from some of the exploited young people who spent their teens travelling around the UK for months at a time living in drugs dens selling heroin and

They do this by taking over the homes of vulnerable people - drug users or the elderly - to sell drugs from and then refuse to leave -a practice called 'cuckooing' which can have tragic consequences.

These trafficked children often find themselves trapped by the gangs unable to escape because of the threat of violence or in order to pay back debts.

Are the authorities are doing enough to protect children from being exploited in this way? Or are they being let down by being viewed as criminals themselves rather

Fifteen years ago, promising young footballer Kevin Nunes was shot dead on a country lane in Staffordshire. Five men were convicted of his killing, and jailed for life. But just four years later, their convictions were quashed, following concerns about the way police handled a key prosecution witness.

The Court of Appeal Judge said it appeared to be "a serious perversion of the course of justice," and an investigation was launched into misconduct claims against four of the UK's most senior officers.

Now, as the report into the police investigation is finally released, File on 4 speaks to those at the centre of the saga. Will the family of Kevin Nunes will ever get the justice they seek, and what does the case tell us about police transparency and accountability?
