Newspaper headlines: Ted Heath abuse probe, City trader jailed and Cilla Black death speculation

There is general agreement in Tuesday's papers that that the ongoing investigation into allegations of historical sex abuse has taken a "dramatic" turn with the revelation that police are now investigating claims made against former Prime Minister Sir Edward Heath.

The Daily Mail focuses on what it terms "sensational claims" Wiltshire Police covered up allegations against the late Tory MP in the 1990s.

Meanwhile, the Sun highlights the "astonishing public appeal" by the same force - which now faces investigation by the police watchdog - asking any alleged victims of Sir Edward to come forward with information.

Prime minister between 1970 and 1974, Sir Edward, says the Times, has become "the most prominent figure" to be accused to date. But it is also among the papers to highlight friends and political allies who have rallied to his defence.

According to the Guardian, the Metropolitan Police have already spoken to a man who says he was abused as a child by Sir Edward on several occasions.

Meanwhile, the Daily Mirror leads with claims by a man that he was raped by Sir Edward after he had run away from home in 1961 when aged 12. The man claims the attack took place at the then MP's flat in central London and says he was "fobbed off" by social workers when he reported the allegations.

In the Daily Telegraph, assistant political editor Rosa Prince says rumours about Sir Edward's sexuality swirled around during his 51 years in the Commons, but a decade after his death they have now taken a more sinister turn.

And Geoffrey Levy in the Daily Mail writes: "Until now, beyond being a juicy vehicle for titillating gossip, the sexuality of Sir Edward Heath hasn't really mattered at all. The dreaded word 'paedophile' risks changing all that."

The conviction of former City trader Tom Hayes for rigging global Libor interest rates prompts calls for further action.

Hayes, 35, boosted his salary and bonus through the offending and "paid the price" for his greed, although banks and regulators are still blocking reforms of the system, reports the Independent.

The 14-year jail term handed down at Southwark Crown Court - the longest given to any banker since the financial crisis - "sent shockwaves through the City", says the Times.

In its leader column, the Times says Hayes received "a stiff sentence and a deserved one". It says the manipulation of Libor, which is used as a benchmark for trillions of pounds of global borrowing and lending, was a "staggering fraud".

The Daily Mail wants executives who benefitted from his actions also to be "held properly accountable for their venal conduct - either in court, or via a long-overdue judge-led inquiry".

The Daily Telegraph says Hayes has paid a "very high price for practices that went far further than him" but the verdict was a triumph for the Serious Fraud Office.

The Financial Times agrees, saying that while Hayes was the first person to be convicted over Libor rigging and the only man in the dock, "he was never the only one being judged".

The FT is also among several papers to profile Hayes, who it says gained a "near-legendary status among his fellow expat traders in the clubby atmosphere of the Tokyo market".

The death of Cilla Black at her villa in Spain on Saturday continues to attract widespread coverage.

An interview the TV star's long-term friend Terry McCann gave to the BBC in which he said her health was failing and she "willed herself to die" is picked up by several papers, including the Daily Star.

The Sun leads with the story, reporting that Black's staff believe the singer and TV presenter suffered a stroke in the heat, shortly after she left her air-conditioned bedroom.

A Spanish police spokeswoman quoted in the Guardian, suggests Black died naturally although an "accident may have been a contributing factor". It follows reports the 72-year-old fell over after suffering a dizzy spell.

However, the Daily Express says a post-mortem examination - while confirming Black's death as non-suspicious - was inconclusive. The Express is among the papers to report on the hundreds of fans paying their respects to Black in a town hall book of condolence set up in her home city of Liverpool, where her "smiling face shone from a giant screen inside while the union flag flew at half mast as a sign of respect and loss".

And the Daily Mirror carries the news of a campaign on social media to get Black's 1964 hit Anyone Who Had A Heart back to number one in the singles chart.

US President Barack Obama's plan to cut carbon dioxide emissions from American power plants by almost a third before 2030 is examined in some detail.

President Obama, says the Independent, unveiled a bold plan which promotes renewable energy but puts climate change at the centre of the political divide in the US.

In the view of the Guardian, the plans are "neither new nor radical, but deserve to be strongly supported, both in America and across the globe".

The Daily Telegraph sees the targets of the revised Clean Power Plan as "ambitious and probably unachievable" but says President Obama "may well have caught the climate change tide just at the right moment" ahead of a December summit in Paris.

In the Financial Times, former BP executive Nick Butler says President Obama has "selected climate change as the next building block in the construction of his legacy".
