LONDON — It wasn’t just President Donald Trump and wife Melania soaking up the royal treatment during their state visit to the United Kingdom. The president’s four adult children inserted themselves into the pomp at every turn.

Whether or not they hold White House posts, Trump’s children were frequently by their father’s side as he was feted in Britain.

Donald Trump Jr. posted on Instagram a photo of himself in white tie before Monday’s state dinner. His brother, Eric Trump, was part of the family’s Tuesday tour of the underground Churchill War Rooms and lingered over the chair from which the prime minister oversaw World War II. And Ivanka Trump, who doubles as a senior White House official, spent the day before her father’s arrival touring some of London’s art museums and then took her place by his side for a trade meeting Tuesday with Prime Minister Theresa May.

“Magical night at Buckingham Palace with my best friend!” she wrote, posting a photo on Instagram of herself alongside husband Jared Kushner, another senior White House aide.

Tiffany Trump, a Georgetown University Law School student who is less frequently spotted with her father, also attended the dinner.

And all four claimed front-row seats at Trump’s news conference Tuesday with May. Only 13-year-old Barron Trump, who lives at the White House with his parents, skipped the trip.

The presence of the sons and daughters raised some eyebrows. While Kushner and Ivanka Trump work in the White House, Eric and Donald Trump Jr. lead their father’s empire, the Trump Organization, and are meant to keep a firewall between the government and the company.
