To Princess Diana’s former butler, Buckingham Palace was the "gin palace," where the drinks never stopped flowing.

Paul Burrell, who served at the royal residence for 11 years before moving to Kensington Palace, has written a new book, "The Royal Insider." In it, he said that gallons of gin were consumed every week, "some legitimately, some not."

"I quickly became familiar with the ingenious ways in which the household smuggled booze for their soirées," he wrote, as quoted by The Sun. "I would be ordered by senior members of staff to empty a screw-top tonic water bottle each night and fill it with gin for them to use for parties in their rooms."

"Footmen could be seen carrying Russell Hobbs electric kettles around the palace, not full of water but full of gin," he added.

Royal experts told Fox News Digital that palace aides weren’t the only ones who loved their libations behind closed doors.

"It was an open secret that the Queen Mother (Queen Elizabeth II’s mother) enjoyed ‘a tipple,’ according to her biographer William Shawcross," Richard Fitzwilliams told Fox News Digital. "She enjoyed ceaseless social rounds and, reportedly, a gin and Dubonnet at noon, red wine at lunch, a martini in the evening and pink champagne after dinner."

"Queen Elizabeth was known to be partial to a gin and Dubonnet, which was her favorite cocktail," he shared. "Princess Margaret was especially fond of Famous Grouse whiskey. It has also been reported that Princess Catherine enjoys an evening gin and tonic. Meghan Markle famously named her blog The Tig after Tignanello, her favorite wine."

In 2021, a family friend told People magazine that Prince William is known for bringing his wife, Kate Middleton, a classic gin and tonic after putting their three young children to bed.

"They look after each other, but in different ways," the friend said.

Occasionally, Kate craves something sweeter, British royals expert Hilary Fordwich told Fox News Digital.

"Princess Catherine always liked vodka, passion fruit and raspberry liqueur, which is much sweeter than most drinks," Fordwich said. "She even finishes it off with a dash of champagne. It was served at her wedding to Prince William."

Even health-conscious King Charles won’t pass up a good dram.

"Charles is a man of healthy habits," Valentine Low, author of "Power and the Palace," told Fox News Digital. "He skips lunch. He has a very light breakfast. But a government minister, Michael Gove, once told me how he went on a trip on the royal train with the then-Prince Charles. In the evening, he was summoned for a nightcap with Charles and was offered a very good malt whiskey — a glass of Laphroaig."

"They had a nice chat about all sorts of things, including government policies," Low said. "And then, at the end of that nightcap, he realized it was time to go when there was a discreet knock at the door.

"The next morning, he was invited to have breakfast with Charles. But before he went, Charles’ private secretary suggested he might want a ‘big boy’s breakfast’ beforehand. So, he joined the private secretary for eggs, bacon and toast. Then he went to see Charles, who offered his own breakfast — a small glass of healthy juice and a few nuts and seeds."

"He had two breakfasts that day," Low added.

Fordwich told Fox News Digital that the monarch, 76, is known to be a "lighter drinker" who occasionally prefers a martini "meticulously prepared with equal parts gin and vermouth." 

When it came to his mother, the late queen, Fordwich said she favored Dubonnet and gin before lunch, wine with her meal and a dry martini in the evening. Sometimes she would indulge in champagne at night. The routine echoed the Queen Mother’s.

Reports said the queen preferred Bollinger champagne, which has held a royal warrant since 1884. Her husband, Prince Philip, was more of a no-frills drinker.

"Prince Philip would not often drink wine at banquets, preferring a bottle of beer instead," royal expert Ian Pelham Turner told Fox News Digital. 

Philip's drink of choice was Boddingtons Bitter.

The royals could generally handle their alcohol — except for one senior member.

"Prince William, rather admirably in my opinion, has the nickname ‘One Pint Willy,’" said Fordwich. "It refers to his low alcohol tolerance, compared to the rather robust drinking habits of the rest of the royal family."

The nickname was given to William by former rugby star Mike Tindall, who is married to the prince’s cousin Zara. He revealed it in 2023 on Rob Burrow's podcast.

"He's not the best of drinkers," said Tindall at the time.

But in his younger days, William had more stamina, said Fordwich.

"He enjoyed a kamikaze shot [during his clubbing days]," she said. "It combines vodka, lime juice and triple sec."

His late mother, Diana, broke from the mold and didn’t have a regular drinking ritual. She was said to enjoy white wine, particularly Chablis, and peach Bellinis at social events.

In 2019, Vanity Fair royal correspondent Katie Nicholl reported that Prince Harry, who was once known for knocking back vodka Red Bull chasers at nightclubs, had adopted a healthier lifestyle thanks to his wife. Today, he reportedly starts his day with a green juice.

Abigail Spanberger, the Democratic candidate for Virginia governor, declined to call on her party’s attorney general hopeful, Jay Jones, to drop out of the race during a Thursday night debate. She stands among many other Democrats who have also declined to do so after text messages surfaced in which Jones fantasized about killing his Republican colleague in 2022.

Jones, a former delegate from Norfolk, Virginia, has faced mounting calls – mostly from Republicans – to bow out of the race for Virginia attorney general. But Virginia Democrats and other party leaders around the country have refused to cave to pressure they are getting to demand Jones drop out. 

The Jones' text message scandal has become a flashpoint in Virginia's elections, particularly considering it came at a time of heightened sensitivity to inflammatory and violent political rhetoric following the assassination of Charlie Kirk and two attempted assassinations of President Donald Trump. 

SPANBERGER EXCORIATED ONLINE AS A ‘COWARD’ FOR REFUSAL TO DITCH ‘UNHINGED’ JAY JONES

Sens. Mark Warner, D-Va., remained silent when asked by Fox News Digital repeatedly if Jones should drop out of the race. Warner was also pressed on whether he would demand Jones return a $25,000 donation made to his campaign in August, or whether he regretted the show of support in light of the controversy about Jones' violent political speech, but he once again averted his gaze and remained silent. 

Sen. Tim Kaine, D-Va., was also unwilling to call on Jones' to drop out. He told Fox News Digital he's still a supporter of the embattled candidate for his state's attorney general seat. "I think those statements were not in character, and he has apologized — I wish other people in public life would sincerely apologize for stuff," the 2016 Democratic vice presidential nominee said. "I've known Jay Jones for 25 years."

Several other Democrats outside of Virginia who were approached by Fox News Digital similarly walked away, or refused to respond when asked about the Jones controversy, which revolves around a text message exchange he had in 2022 with another lawmaker. 

During the texts, Jones fantasized about putting "two bullets" into the head of then-Virginia House Speaker Todd Gilbert. He also quipped about murdering Gilbert's children.  

"Three people, two bullets. Gilbert, Hitler and Pol Pot. Gilbert gets two bullets to the head," Jones wrote. In a subsequent text, Jones also wrote, "Spoiler: put Gilbert in the crew with the two worst people you know and he receives both bullets every time."

"Jay. Please stop," the lawmaker on the receiving end of the tests from Jones said at the time. Jones has since apologized, calling the remarks "embarrassing and shameful," and said he had reached out personally to Gilbert and his family.

"I’m really not familiar with the situation in Virginia," Sen. Richard Blumenthal, D-Conn., said when asked if Jones should drop out. 

"Haven't given it a thought," said Sen. Sheldon Whitehouse, D-R.I. 

Meanwhile, Sen. Ron Wyden, D-Ore., called the texts "horrifying," but when pressed further on whether Jones should drop out, Wyden said, "I’m going to leave it at that, thank you."

SANDERS, DEM LEADERS DODGE QUESTIONS ON VIRGINIA CANDIDATE WHO JOKED ABOUT SHOOTING GOP LAWMAKER 

Other Democrats who Fox News approached, such as Sens. Andy Kim, D-N.J., and Martin Heinrich, D-N.M., condemned political violence but admitted they were not following the matter involving Jones. 

"I can't say that I've done my due diligence to really understand, but what I will say is that what I saw was absolutely horrible," said Kim. "I hope that in a time right now, where there's so much concern about political violence, we can say that, ‘Yes, we need to make sure that we are holding ourselves up to a high standard, especially those in elected office.’"

Republican responses to the Jones text scandal were starkly different. Speaking with Fox News Digital, Sen. Ted Cruz, R-Texas, called the text messages "staggering, particularly with the spate of political violence we have seen." 

"There are far too many on the left that celebrate political violence," Cruz continued, adding, "When Charlie Kirk was assassinated, we saw leftists, college professors, leftist schoolteachers, politicians, journalists celebrating that heinous murder."

"And every Democrat in Washington is turning a blind eye," Cruz added. "In my view, the notion that someone advocating for the murder of children because he disagrees politically with their father is manifestly unsuitable for public office, especially the chief law enforcement officer of Virginia. And I wish there were even one Democrat with the courage to say that publicly."

"It's really sickening calling for the assassination of a rival, calling for the death of his children. I mean, I think, hopefully, all of us can agree that's beyond the bounds of what is reasonable here, and he ought to step down," Sen. Eric Schmitt, R-Mo., said when asked about the controversy. "What's amazing though, is, I've not heard one Democrat – hopefully you're asking that question to other Democrats. I've not heard anybody say anything about it, which is pretty sad."

During a debate Thursday night between Republican and Democrat candidates for governor in Virginia, Republican candidate Winsome Earle-Sears repeatedly pressed her Democratic opponent, Spanberger, to call on Jones to step down. 

"Jay Jones advocated the murder — Abigail — the murder of a man, a former speaker, as well as his children who were 2 years and 5 years old. You have little girls. Would it take him pulling the trigger? Is that what would do it?" Earle-Sears asked Thursday night. "Please ask him to get out of the race. Have some courage."
