The papers are named after the Greek myth of Pandora’s box.

In the tale, Pandora opens a sealed box containing the forces of evil and suffering which, once released, were uncontainable.

Gerard Ryle, the director of the International Consortium of Investigative Journalists(ICIJ) - which organised the world-wide investigation of the files, says this leak was given the name because “we're opening a box on a lot of things”.

Chancellor Rishi Sunak has also been speaking to Sky News about the Pandora Papers leak, telling the broadcaster that the UK's tax department will take a look at the files.

"HMRC (HM Revenue & Customs) will look through those [documents] to see if there is anything we can learn," he tells Sky News.

Mr Sunak says the UK "led the world" in improving the sharing of information between tax authorities and law enforcement agencies.

"But as the papers showed, this is a global phenomenon," he says, adding: "We can do our bit, but we require other countries to co-operate with us as well and you will continue to expect us to press on that."

Still speaking to Radio 4's Today programme, Chancellor Rishi Sunak says the UK leads the world in tackling money laundering, after the Pandora Papers revealed tens of millions of pounds worth of UK properties owned offshore by foreign leaders.

The leak has highlighted the UK government's failure to introduce a register of offshore property owners despite repeated promises to do so, amid concerns some property buyers could be hiding money-laundering activities.

Mr Sunak tells BBC Radio 4's Today programme: "The independent global body, the Financial Action Task Force, has said that we are one of the best in the world at [tackling money laundering].

"But as you've seen from the papers, it is a global problem. There's a global dimension to it, and we need other countries to co-operate with us to tackle this. But we are determined to do that and our track record on this is very strong."

Today puts it to the chancellor that official figures show that half of all Russian money laundering happens in this country.

Mr Sunak replies: "Yes and the independent global body FATF said when they last looked at us in 2018 we were probably one of the best places in the world to tackle money laundering - there is always more we can do."

We've got more from Chancellor Rishi Sunak on the Pandora Papers.

He insists the UK has one of the best track records on tackling tax avoidance after the documents revealed how wealthy people from overseas set up companies to buy millions of pounds of properties here.

Asked if it is a source of shame that many people call London the tax avoidance capital of the globe, he tells BBC Radio 4's Today programme: "I don't think it's a source of shame because actually our track record on this issue is very strong."

He says the UK leads the world in "improving transparency - making sure we know who owns things" and "exchanging data between tax authorities or enforcement bodies".

However, this is not a view shared by all.

Duncan Hames, director of policy at Transparency International UK, says the revelations must act as a "wake-up call for the government and regulators" in the UK.

“Once again, Britain’s role as an enabler of global corruption and money laundering have been exposed with the same loopholes exploited to funnel suspect wealth into the country," he says.

“The UK must redouble its efforts in tackling illicit finance, bringing in long-overdue transparency reforms to reveal who really owns property here as well as resourcing regulators and law enforcement to clamp down on rogue professionals and corrupt cash held in the UK.”

The UK government is determined to tackle the problem of rich overseas investors buying up UK property to avoid paying taxes, the chancellor says.

The Pandora Papers revealed how prominent and wealthy people have been legally setting up companies to secretly buy property in the UK.

Rishi Sunak tells BBC Radio 4's Today programme it is a global problem and "there is more we can do".

More than 600 journalists in 117 countries have been involved in investigating the Pandora Papers. The BBC is one of over 140 different media organisations to cover the leak.

Here's a snapshot of how some other news websites are covering the story.

The Pandora Papers leak has once again cast a spotlight on the funding of UK political parties by wealthy donors.

As we mentioned earlier, a major Conservative Party donor features prominently in the files.

So, how do donations work?

Electoral Commission rules, external mean any donation over £7,500 to a party has to be reported by that party, and the figure and the donor will be published.

The commission says it is up to the political party, individual or other organisation to check if the donation or loan is from a permissible source, and if they can accept it or not.

At present, donors only need to be on the UK electoral register. Once a party has checked that, they can accept as much money as they like.

You can read more about political party donations, and why they are so often controversial, here.

Chancellor Rishi Sunak has told the BBC that the Conservative Party carries out all legal background checks on its donors after the Pandora Papers showed a prominent supporter was involved in one of Europe's biggest corruption scandals.

The papers show Mohamed Amersi, who has given nearly £525,000 to the party since 2018, worked on a series of controversial deals for a Swedish telecoms company that was later fined $965m (£700m) in a US prosecution.

Speaking before his first speech as chancellor at the Conservative Party Conference in Manchester, Sunak tells BBC Breakfast: "My understanding is we that carry out compliance checks in line with the referendums and political parties legislation that was put in place by the Labour government.

"Those are the compliance checks that are required by law. Those are the compliance checks that the party carries out."

A parliamentary report published earlier this year, external recommended steps to address the "risk that the current rules on donations from companies provide a route for foreign money to influence UK elections".

Another revelation from the Pandora Papers now.

The family of Kenya's President Uhuru Kenyatta secretly owned a network of offshore companies for decades, according to the leak.

Mr Kenyatta and six members of his family have been linked to 13 offshore companies in Panama and the British Virgin Islands.

One company owned by his brother had stocks and bonds worth $30m (£22m).

The president and his family have not yet responded to requests for comment.

The documents also show that a foundation called Varies was set up in 2003 in Panama, naming Mr Kenyatta's mother, Ngina, 88, as the first benefactor - and Kenya's leader as second benefactor who would inherit it after her death.

The purpose of the foundation and the value of its assets are unknown.

In 2018, Mr Kenyatta told the BBC's HARDtalk programme that his family's wealth was known to the public, and as president he had declared his assets as required by law.

"As I have always stated, what we own - what we have - is open to the public. As a public servant I'm supposed to make my wealth known and we declare every year," he said.

"If there's an instance where somebody can say that what we have done or obtained has not been legitimate, say so - we are ready to face any court."

The Guardian joins several other newspapers to lead with the Pandora Papers leak, which has exposed the dealings and secret wealth of world leaders, politicians and billionaires.

The Guardian, along with the BBC's Panorama programme, led the investigation in the UK and today publishes 11 pages of reporting on the huge leak of financial documents., external.

Among the revelations is how the King of Jordan secretly amassed £70m of UK and US property, Russian President Vladimir Putin's link to secret assets in Monaco and how former UK Prime Minister Tony Blair and his wife saved more than £300,000 in stamp duty when buying a £6.45m London townhouse.

We’ll soon be hearing from Chancellor Rishi Sunak on BBC Breakfast and Radio 4’s Today programme.

Today’s stories - incuding one about a prominent Tory donor - are unfolding as the Conservative Party Conference kicks off in Manchester.

This is where politicians, party members and potential donors gather for events and keynote speeches, as the party tries to rally support and raise funds.

Boris Johnson will be there alongside his fresh line up of ministers and thousands of party members. We’ll bring you all of the reaction from the conference as we get it.

As we mentioned, hundreds of journalists have been digging into these documents. Here are some of the stories that have been uncovered:

• The King of Jordan spent more than £70m on 15 overseas homes - while the country he rules over is given hundreds of millions of pounds in aid by the UK and US
• Azerbaijan’s ruling family, the Aliyevs, secretly acquired UK property using offshore companies, including a £30m London office block for the president’s 11-year-old son
• Former UK Prime Minister Tony Blair and his wife Cherie purchased a London office by buying an offshore company. While there is no suggestion the Blairs hid their wealth, the structure of the deal meant they did not have to pay £312,000 in UK tax
• Prominent Tory donor Mohamed Amersi, who contributed to Boris Johnson's leadership campaign, was involved in one of Europe's biggest corruption scandals
• The leak also links Russian President Vladimir Putin to secret assets in Monaco, and shows the Czech Prime Minister Andrej Babis - facing an election later this week - failed to declare an offshore investment company used to purchase two villas for £12m in the south of France

Mr Amersi denies any wrongdoing.

The 61-year-old is a corporate lawyer who worked as a consultant for Telia between 2007 and 2013.
