According to the Times, the latest leak of offshore tax avoidance records tarnishes capitalism and will have dire political consequences unless governments act fast.

The Guardian talks of "outrage" as the scale of tax avoidance "by the global elite is laid bare",
Max Hastings, in the Daily Mail, says the naked greed of the tax avoiders is playing straight into Jeremy Corbyn's hands.

It says "most of what's disclosed does not amount to unethical, yet alone illegal, activity".

F1 world champion Lewis Hamilton, who reduced his tax bill on a private jet by importing it to the Isle of Man, is on the front of Germany's Suddeutsche Zeitung, which had the original leaks of the Paradise papers.

"And damn," says the paper, "how the multimillionaire must love the Isle of Man".

The US Commerce Secretary, Wilbur Ross, is the main focus of the Daily Telegraph's front page - but not in connection with revelations about his Russian business links.
The paper says he's warned that Britain should avoid too much compromise with the EU in Brexit negotiations.
In an interview, he told the Telegraph that a trade deal between Britain and the US could be signed "within months".
The Daily Express commentator, Ross Clark, is concerned about reports that ministers have indicated they are prepared to pay a leaving bill of £53bn in order to move the talks along.

The Korean Times welcomes President Donald Trump's two-day visit, which it says will be a crucial point in dealing with North Korea's nuclear and missile ambitions.
It says his first destination on the trip - to Camp Humphreys, the newly established headquarters of the US 8th Army - will enable Mr Trump to witness South Korea's commitment to the alliance between the two countries.
The Korea Herald points out the visit comes exactly a year after President Trump's election to the White House.
It says officials in Seoul are mulling over how best to congratulate Mr Trump without wine or champagne at a state dinner, as the US leader does not drink.
