Meghan Markle has shared a series of 'summer holiday' photos of Prince Harry and their children Archie and Lilibet while in Europe – including what appears to be a visit to Princess Diana's childhood home. The family had been visiting Europe in recent weeks ahead of Prince Harry's return to the UK this month to attend the Invictus Games in Birmingham where he had intended to bring Meghan and their two children with him for the entirety of the five-day trip.Instead, the Duke of Sussex flew to Britain alone, and hours before he arrived in London, chaos erupted when an invitation to stay at Buckingham Palace was withdrawn.The Duchess of Sussex delayed her arrival and entered the country secretly with Archie, seven, and Lilibet, five, amid ongoing security concerns.It was not confirmed where they had been vacationing but it was widely believed to have been in Portugal, where the Sussexes reportedly purchased a second property near Harry's cousin, Princess Eugenie and her husband Jack Brooksbank.Indeed, in one of the posts shared to her Instagram, Meghan shared the image of a front of a Portuguese fish restaurant, O Melidense. Another post from the carousel is believed to show the family visiting Althorp, Princess Diana's childhood home.In the shot, Lilibet was seen walking through an avenue of trees and hedges, with Harry and Archie strolling together up ahead appearing to hold bouquets.

Harry and his family are believed to have met the King and Queen for more than an hour. The visit to Highgrove came after a chaotic back-and-forth about where Prince Harry would stay during his trip.The King is said to have lost patience when Harry dithered over an offer to stay at Buckingham Palace at the start of his trip.The Duke initially rejected the accommodation before changing his mind and attempting to accept after the deadline had passed.Harry's spokesman subsequently briefed the BBC that he would be staying at the Palace, only for the King's aides to indicate that he had left it too late.
