Members of the public got to within just 10ft of the Duke and Duchess of Sussex’s private residence in Windsor today as Frogmore House was opened up to visitors for a second day in a row. Insiders at the historic royal residence said they were surprised that the public open days went ahead at all following the birth of Prince Harry and Meghan’s first child Archie just three weeks ago on May 6. Kensington Palace would not say whether Harry and Meghan were there but the Duke of Sussex had an engagement with the Queen at Buckingham Palace this afternoon. Hundreds of history buffs and royal enthusiasts paid just £7 to access the historic Victorian property as part of its annual open day, and were made to go through airport style security flanked by Metropolitan Police officers. Portable loos were brought in for the public as well as a marquee with a stall selling cake and hot drinks.
