While the website of the royal family describes consent as "a long established convention", The Guardian newspaper reported in February 2021 that memos had been found in the National Archives revealing that the advance notice of forthcoming bills allows the monarch to lobby for legislative changes without actual consent being invoked. The documents were reviewed by Thomas Adams, a specialist in constitutional law at Oxford University, who said they revealed "the kind of influence over legislation that lobbyists would only dream of", adding that the existence of the consent procedure appeared to have given the monarch "substantial influence" over draft laws that could affect her. As of 2021, over 1000 bills had been submitted to the Queen or Prince Charles for Queen's or Prince's Consent.[27] More than 50,000 people had, by 28 February 2021, signed a petition requesting a parliamentary inquiry into the convention of Queen's Consent.[28] Buckingham Palace responded to The Guardian, stating that consent was always granted when requested and that legislation was never blocked.[3]
