Will the Rana Plaza factory tragedy mean Bangladeshi garment workers no longer have to work in death traps? It's five months on from the collapse of the 8 storey building in Dhaka, in which more than a thousand workers died, and several thousand lost arms or legs or were paralysed. Jane Deith reports from Dhaka on what's happened since. Just how much medical and financial help have survivors and families of the dead received?

Campaigners said the disaster should be a "game changer" in forcing international brands who source cheap clothes in Bangladesh to take more responsibility for conditions within the factories they use. Safety inspections of hundreds of premises are due to begin in earnest. But the Western manufacturers are split on who should pay for expensive improvements - the clothing brands or the factory owners? It's estimated that it could cost $3bn to bring all the factories up to scratch.

But there are those who argue that Western shoppers who buy the cheap clothes, and the brands that sell them, don't deserve all the blame. The Bangladeshi government continues to limit the power of trade unions and is accused of failing to act against powerful manufacturing bosses when people die in their factories.

The safety campaigners agree that Western brands pulling out of Bangladesh would be the worst result for the country's four million garment workers and the families who rely on their earnings.

So is it possible to keep them in work and keep them safe?

Psychiatric hospitals have a duty to keep their patients safe, which means taking extra care with patients suffering acute depression who may be at risk of self-harm.

So campaigners argue that when a patient commits suicide, it is vital that a thorough investigation should discover any failings by doctors and nurses and any weaknesses in hospital systems of communication or levels of staffing.

But, unlike deaths in prison or police custody, fatalities in psychiatric units are not reviewed from the start by a fully independent investigator. Initial reports are usually prepared by staff of the NHS and kept confidential to the health officials and family concerned. Only at the subsequent inquest does an independent inquiry take over.

Critics call this 'a recipe for cover-up by the NHS'.

File on 4 reports on a series of suicides in one psychiatric unit which have led the local coroner to accuse the NHS of 'a catalogue of failures stemming from an institutional complacency'.

The amount of coal burned in Britain's power stations rocketed in 2012 with ministers relying on the fuel to help keep the lights on in the next few years.

Last week, the Government dropped plans to introduce plain packaging for cigarettes in England. It said it wanted to wait and see what happens in Australia where the measure was introduced earlier this year.

While the G8 summit of world leaders has agreed a global deal to ensure big business pays its dues, concerns about tax avoidance go wider.

A group of MPs has just examined the case of the Cup Trust, a charity which tried to claim £46 million in tax relief but spent just £55,000 on good works. The Chair of the Public Accounts Committee, Margaret Hodge, concluded the Trust's purpose "was to avoid tax".

And she said this wasn't an isolated case. The Committee heard that HMRC investigates around 300 charities a year over concerns about tax fraud.

In this week's File on 4 Fran Abrams examines the blurred lines around charities and tax.

What happens when genuine charities find 'donations' are designed so the donors can claim Gift Aid payments from the tax man? And how easy is it to register a charity whose main aim is actually tax avoidance?

Is the 160 year-old Charity Commission up to the job of policing 21st Century charities?

NHS hospitals in England are back in the spotlight with a crisis in A&E and a growing number of cancelled operations. But does the real problem lie in the way the Government is currently funding them?

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.
