File on 4 Investigates

Ebola is now regarded as an international threat to peace and security, according to the World Health Organisation. Yet, when the WHO was first warned of an unprecedented outbreak, the organisation said it was "still relatively small."

In the biggest outsourcing to date, the NHS in England has announced it is tendering a huge £700 million contract for providing NHS cancer care in Staffordshire and Stoke-on-Trent, along with another £500million for end of life care in the region. Officials say it will streamline services and provide better treatment while critics say it's the most reckless privatisation yet. BBC Health Editor Hugh Pym investigates..

The nature of crime is changing, with much of it now happening online, sparking growing concern that official figures fail to account for potentially millions of fraud offences. Experts say frauds involving plastic debit and credit cards are among the crimes left out of the data. So just how reliable - and useful - are the statistics?

At the same time, police economic crime units, which investigate fraud, have become increasingly stretched, partly as a result of government budget cuts. BBC Home Affairs correspondent, Danny Shaw, asks whether law enforcement has kept pace with the changing face of fraud and if there are enough resources to tackle financial crime and bring fraudsters to justice.

How well are Britain's borders patrolled and defended at a time when the authorities are battling to stem the flow of illegal immigrants coming across the Channel and tightening national security because of fears of a terrorist attack by extremists returning from fighting in Syria and Iraq?

Is a new scandal about to engulf the UK's banking industry? Was LIBOR just the tip of the iceberg?

Knowl View special school for boys has become infamous as the haunt of Cyril Smith. Prosecutors now say 'Mr Rochdale' should have been charged with abuse of boys while he was alive. But he was not the only one. In the first of a new series, former pupils in the 1970s, 80s and 90s tell File on 4 how a web of abusers, including local paedophiles and other pupils preyed on boys as young as eight while people supposed to protect them looked the other way. Previous police investigations came to nothing. A new probe is underway, focusing on who could be guilty of a criminal cover up. But what became of the innocent? Jane Deith hears from some of those who experienced life in Knowl View. Telling their stories for the first time, they describe childhoods twisted by sexual abuse. Now questions are being asked about whether the failure to end the abuse at Knowl View led to a culture in which the subsequent grooming of young girls in Rochdale was allowed to happen. Alan Collins, a specialist child abuse lawyer representing some of the men who're suing Rochdale Council over abuse at Know View, believes things would have been different had Cyril Smith been prosecuted and convicted: "That would have sent a clear message through Rochdale and much further afield that there was clearly a problem and that problem would not have been so easy to brush away. I think that had a very long tail and that that tail continued right up until recent times."

Every year more than 1,500 UK children are diagnosed with cancer.

Last month, in the Queen's Speech, the Government announced a series of measures to support small businesses -- including proposals to deal with the problem of late payment of bills by larger companies.

It follows a long history of horror stories about major high street names leaving suppliers and sub-contractors out of pocket because of delays in settling accounts.

Figures produced by the Department of Business, Innovation and Skills revealed that 85 per cent of small and medium sized businesses said they had experienced late payment in the last two years and that, in total, there was £30bn outstanding to them.

But File on 4 has found that it's not just in private business that serious problems are occurring.

The programme speaks to business owners who say that that ineffective rules and sanctions have left them badly out of pocket on contracts undertaken in the public sector.

Local authorities, the NHS and other Government departments have strict rules about how long they should take to pay their contractors.

But Jenny Chryss reveals how some small firms are having to cut back on staff because bills still aren't being settled promptly.

And she reveals how big contractors who do get paid on time, often delay before passing the money down the supply chain.

So are critics right when they say the Government's proposed new measures still aren't enough to deal with the problem?

In many parts of the world, charities are trying to deliver much-needed aid to desperate people living in areas controlled by militant groups. What do they do when counter-terrorism laws ban them from contact with those de facto authorities?

Risk of prosecution has now created a climate of fear in many aid agencies - and the UN wants counter-terrorism policies redrawn to ensure lives can be saved without charity workers risking jail.

Tim Whewell reports from Gaza - and talks to aid workers operating in Syria, Somalia and other places - on the practical and moral dilemmas involved.

On the day a parliamentary committee is due to take evidence about the Yarl's Wood immigration removal centre, Simon Cox investigates claims of sexual abuse and poor health care for the women held there.

Campaigners and detainees tell File on 4 about "a culture of disbelief" which they say exists among healthcare staff and which they claim is putting women at risk.

Serco - the company that runs the centre - insists it provides a good standard of care, but a former member of staff, speaking publicly for the first time, says concerns he raised were ignored by senior managers.

The programme also investigates claims of inappropriate sexual contact between staff and detainees and allegations of sexual abuse by staff.

Several employees were dismissed last year over sexual encounters with women being held at the centre and the House of Commons Home Affairs select committee have called the managing director of Serco to give evidence about the sexual abuse claims.

Simon Cox investigates - and hears why some MPs believe it is time for the centre to be closed.
