By special order of his mother Queen Elizabeth, the Prince of Wales stepped in to undertake the important duty of giving the Queen's Speech at the State Opening of Parliament on Tuesday. The Queen, 96, was unable to attend amid ongoing mobility issues. With his son, Prince William, in attendance for the first time, Charles carried out the duty that his mother has done all but two times in her 70-year reign. Charles has accompanied his mother the Queen to the State Opening of Parliament, but Tuesday marked the first time that he — along with his son William — represented the monarch in her absence. Charles' wife, Camilla, Duchess of Cornwall, was also in attendance at the Houses of Parliament in Westminster, London. For more on Prince Charles addressing Parliament, listen below to our daily podcast PEOPLE Every Day. On Monday, Buckingham Palace announced that the monarch had issued what's known as a Letters Patent to delegate the task to her son and grandson, her two immediate heirs.

The two princes are Counsellors of State and are two of only four people she could ask to perform the constitutional duty. "The Queen continues to experience episodic mobility problems, and in consultation with her doctors has reluctantly decided that she will not attend the State Opening of Parliament tomorrow," Buckingham Palace said in a statement on Monday.

While Queen Elizabeth wasn't there, the Imperial State Crown was still present. The historic crown, which symbolizes the sovereignty of the monarch and is only seen at coronations and state openings of Parliament, was placed on a red velvet cushion to the right of Charles. The Queen has stopped wearing the heavy crown in recent years (it weighs over two pounds), and instead has it seated next to her during the ceremony. Charles took his place on Consort's Throne — the Sovereign's Throne, which is slightly taller and used by the Queen, had been removed. Prince William.

The Imperial State Crown was placed prominently on a table between the two princes. Charles continued the 11-minute speech, which outlined the administration's objectives. He used the often repeated phrase "Her Majesty's government" instead of "My government," which is what the Queen would use if she had delivered the speech. Charles concluded the speech with a reference to how "Her Majesty" was looking forward to the celebrations that will mark her Platinum Jubilee next month and the upcoming Commonwealth Games in August. "Her Majesty prays that the blessings of Almighty God will rest upon your counsels," he said. Prince Charles and Camilla, Duchess of Cornwall.

Prince William and his equerry followed shortly behind. A short burst of the national anthem, "God Save The Queen," played as the royal cars drove away. The Queen, who has been forced to cancel many official engagements since the fall, has been using a walking cane and even complained about mobility problems, joking during an in-person meeting: "Well, as you can see, I can't move!"

The palace has consistently announced the Queen's attendance or absence from planned events just hours before her expected arrival in recent months. Queen Elizabeth.

She undertook a call with Australia on Monday and has a planned Privy Council and Prime Minister audience on Wednesday. She's also expected to undertake some private engagements later in the week, according to the palace. The Queen's annual garden parties will kick off this week at Buckingham Palace, but the monarch will not be in attendance. Other members of the royal family will greet some of the 8000 guests who gather on the back lawns of the palace in central London. Can't get enough of PEOPLE's Royals coverage?
