The Queen Had to lead, and her husband must follow.
Prince Philip married Queen Elizabeth II, but even that didn’t make him equal to his wife. According to the orders of the precedence of United Kingdom, The Prince always had to be at a distance of a few steps behind his wife, especially during occasions that were formal and state dinners and as the Queen given the status of the sovereign, had to walk in front of any processions.
t was the Queen and her husband itself, but still, the Royal had rules and restrictions applied to them. Although he had the status higher than all-male members, Prince still could not surpass the status of a queen and walk beside her, let alone walk in front of her. After all, being Royal comes with the price to pay.
