Prince Philips's brutal opinion of Sarah Ferguson revealed in bombshell book

In a shocking reveal, the late Prince Philip is claimed to have questioned Sarah Ferguson's motives for marrying Prince Andrew in a new bombshell book set to be released later this month. 'Entitled: The Rise and Fall of the House of York' is a new book by royal author Andrew Lownie, which draws on four years of research.

The description reads: "The book traces the lives of the late Queen's second son and his ex-wife through their childhoods, courtship, marriage, divorce, careers, and royal and charitable activities." Serialised extracts have been published in the Daily Mail, and in shocking claims reveal, "The Duke of Edinburgh just thought she was a girl on the make".

A "well-connected" source of the author stated: "Fergie couldn't stop talking - and inappropriately. She was all high jinks, jolly hockey sticks and practical jokes. Andy loved it, no one else did. The Queen said to someone, 'Does that girl never stop talking!' The Duke of Edinburgh just thought she was a girl on the make."

Previously, Sarah has opened up about the fractured bond between her and Prince Philip while speaking to chat show host Alan Carr on the latest episode of his Life's A Beach podcast. According to the Daily Mail, when asked if Philip was a wise man, she replied: "Yes, very wise. You had to be on your best. If you asked a silly comment, you were certainly told it was a silly comment."

Sarah Ferguson is also alleged to have sought out a romance with Tiger Woods after her divorce from Prince Andrew. According to the author, Fergie confided to Piers Morgan that she found the pro golfer "gorgeous" and flew 1,500 miles to meet him.

In extracts serialised in the Mail, Mr Lownie claimed that the Duchess of York had a list of men whom she was keen to be romantically involved with after divorcing Prince Andrew in 1996.

This also included the late son of John F Kennedy, the former US president. Lownie wrote: "On a trip to New York, Fergie asked her staff to find out if John F Kennedy Jnr... was in town and, discovering where he was, she invited him for drinks or dinner at her hotel, which he accepted."

The Duchess was pictured hugging Woods in 1997 following his win at the Byron Nelson tournament in Texas, one of his early PGA Tour victories.

The Duchess of York, who continues to live with her ex-husband, Prince Andrew in Royal Lodge, separated from Prince Andrew in 1992.

One of her most infamous incidents included a photograph surfacing of Fergie sunbathing while having her toes sucked by her financial adviser in St Tropez.

Among the most headline-making claims, the book also alleges that Prince Andrew and Prince Harry, once got into a heated argument at a family gathering in 2013 that escalated into a physical fight, leaving Andrew with a bloody nose.

The excerpt also alleges that Andrew later insulted Meghan Markle behind the scenes, calling her an "opportunist" and casting doubt on the longevity of the couple's marriage. In response, Prince Harry's spokesperson firmly denied both allegations.

'Entitled" The Rise and Fall of the House of York' is set to be released on August 14.
