The statement read: “The Queen continues to experience episodic mobility issues and has reluctantly decided, in consultation with her doctors, that she will not attend the State Opening of Parliament.
“At Her Majesty’s request and with the agreement of the relevant authorities, the Prince of Wales will read the Queen’s speech on behalf of Her Majesty, in the presence of the Duke of Cambridge.
“The Queen had to sign a new patent to have Prince Charles read her speech at the State Opening tomorrow. He does that as Secretary of State.
“Prince William joins him as two councilors of state required to carry out one of the Queen’s constitutional duties.”
