In his 12 years working with the royal family, Dickie Arbiter had a unique insight into the life of Queen Elizabeth and her husband Prince Philip.
Arbiter worked as the Queen's press secretary from 1988 to 2000, and says she and the Duke of Edinburgh were "terrific" to work with.
Speaking to Today for Philip's 99th birthday on Wednesday, the now-royal commentator shared some of his memories and observations of Her Majesty's beloved husband.
"I remember on walkabouts, the Queen would be doing her walk and be way ahead and Prince Philip would be about 50 metres behind," he recalled.
"If you heard raucous laughter, it was a whole crowd of women around him, behind a barrier, and he'd be talking to them and joking with them."
Arbiter said if the well-wishers had children with them, Philip would go the extra mile to make them feel involved.
"He'd lift the children over the barrier, take their hands, walk them down to the Queen so they could hand over their flowers, and then take them back to their mothers," he continued.
"He was a people person, and he is a people person ... he retired in 2017, and that's the sadness of it, people miss him."
Since his retirement, Prince Philip has rarely been seen in public, with the exception of family events — like the respective weddings of his grandchildren Prince Harry and Princess Eugenie in 2018.
He had remained at the royal family's Sandingham estate, but was transferred to Windsor Castle to self-isolate with the Queen when COVID-19 hit the United Kingdom.
The couple have remained there since March, with Philip issuing a rare statement in April to praise the efforts of health professionals and frontline workers during the pandemic.
Their isolation has spanned numerous special occasions, including the Queen's birthday and coronation anniversary, the birthdays of several of their grandchildren, and now Philip's 99th birthday.
The royal family has marked the occasion by sharing a portrait of the couple taken on the Windsor Castle quadrangle last week.
Though 99 is an impressive milestone, Arbiter said it was unlikely Philip would receive any major gifts from his wife of 72 years.
"They'll have a quiet lunch and he might get something small from the family, but I think the biggest present of the lot would be the family around him," he added.
"We're still in partial lockdown and social distancing here in the UK, so that won't happen. But there will be video calls — he's into technology, he's a man of our time."
