veteran royal correspondent Robert Jobson, the book’s author, has accompanied the prince for 18 months on tours around the world.
Mr Jobson, who has reported on the royals for almost three decades, has spoken to many current and former members of his staff – and to Charles himself.
The result is a compelling book full of ground-breaking new material which is being serialised in the Mail today and next week.
Among the sensational revelations are:
■How Charles is already ‘Shadow King’ and the Queen could stand aside at 95, allowing him to become Regent.
■How shocked Charles was by his sons’ level of belligerence;
■His dismay at being excluded from the boys’ 2017 documentary about Princess Diana;
■Harry’s meltdown ahead of his wedding to Meghan Markle;
■How Charles ‘talks to the dead’, including Earl Mountbatten, his mentor murdered by the IRA;
■His disdain for Tony Blair, whom he once mockingly referred to as ‘our magnificent leader;’
■His despair at the Iraq War, telling friends Mr Blair had behaved like George Bush’s poodle;
■How he disagrees with the burka bans introduced by France and other European countries;
■His distrust of US evangelicalism and the lobbying power of giant American corporations;
■His fear that America’s chemically-gown corn was fuelling that country’s ever-growing obesity and diabetes crisis;
Charles emerges from this powerful portrait as a contented figure, who is far from bitter but has strong views on some of the most vital issues facing us today.
But it is the revelation about his heartache over Diana that is bound to raise eyebrows.
Ever since Diana confided in biographer Andrew Morton we have known that the princess wanted to back out of the marriage.
