King Charles speaks to Princess Charlotte and Prince Louis while watching the Trooping the Colour ceremony from the Buckingham Palace balcony. Multiple outlets, citing a lip reader, report the king advises Charlotte on when to wave during the Red Arrows flypast. One reported exchange has Charlotte asking whether it is time to wave, with Charles responding that it is, and that they should “give a wave.” The same lip-reading account says Charles also instructs other family members to wave to onlookers.
Other reported moments involve Prince Louis and the Wales family. The lip reader account shared by several outlets includes Kate Middleton reminding Louis of proper posture for the national anthem, with Louis standing as instructed. Charles and Prince William are also described discussing an aircraft during the flypast, with William and George reportedly identifying a “Poseidon.” Overall, the reports portray the royal balcony moments as guidance on ceremony etiquette during the annual military parade marking the sovereign’s official birthday.
