Alex’s questions come in the wake of the Sussexes visiting the Queen as well as Prince Charles last Thursday before the Invictus Games opening ceremony.
It is the first time the pair have been in Britain together since quitting their roles as senior royals in March 2020.
Harry and Meghan now reside in California with their young son Archie and 10-month old daughter Lilibet.
Lilibet was named after her great-grandmother the Queen, but the monarch has not yet met the baby.
Harry, who missed Prince Philip’s Westminster Abbey memorial service on March 29, had promised he would see the Queen “as soon as possible”.
