A royal biographer has revealed Prince Philip had "only one complaint" about Queen Elizabeth II during their 73-year marriage. 

According to Gyles Brandreth, the Duke of Edinburgh - who died aged 99 on April 9 - would moan her majesty was "always" chatting on the phone. 

Speaking on the UK morning TV show Lorraine, Brandreth - who was friends with Prince Philip for roughly four decades - provided some insight into his and the Queen's longlasting union.

Brandreth said the Duke would often say: "God, she's never off the phone. Never off the phone. Who is she talking to?"

Brandreth noted it was "the only time he ever complained about the Queen" throughout their 73-year marriage. 

Her Majesty, who turned 95 on Wednesday, often calls her racing manager in the evenings to discuss horses, Brandreth continued. 

He added that Phillip, who was Britain's longest-serving consort, always supported his wife. 

"He knew his whole life was supporting the Queen, he never put a foot wrong, he always turned up - right day, right uniform, on time, one step behind her."

Philip and the Queen, then referred to as Princess Elizabeth, married three months after their engagement in 1947. The Queen spoke highly of her husband, publicly describing him as her "rock".

The couple celebrated their 73rd wedding anniversary in November 2020.

The Duke stepped down from official engagements in August 2017 after completing more than 22,000 solo events and thousands more alongside the Queen. During his lifetime, he visited New Zealand 15 times.

He was laid to rest on April 17 at St George's Chapel. His naval cap and sword lay on top of the coffin, which was covered with the Duke of Edinburgh's personal standard featuring the Danish coat of arms, the Greek cross, Edinburgh Castle and the stripes of the Mountbatten family.

COVID-19 restrictions in the UK meant no more than 30 people could attend the funeral, requiring the Queen to socially distance while wearing a mask.

Heartbreaking pictures of Her Majesty sitting alone at Philip's funeral flooded social media following the service.

The monarch has been widely praised for showing grace and dignity during one of her darkest moments.
