When a bill becomes law in the United Kingdom, in which language is the formal approval pronounced?

"La Reyne le veult" ("The Queen wills it") is a Norman French phrase used in the Parliament of the United Kingdom to signify that a public bill (including a private member's bill) has received royal assent from the monarch of the United Kingdom. It is a legacy of the time prior to 1488 when Parliamentary and judicial business was conducted in French, the language of the educated classes after the Norman Conquest of 1066. It is one of a small number of Norman French phrases that continue to be used in the course of Parliamentary procedure. The phrase is used by the Clerk of the Parliaments in the House of Lords, after the Lord Chancellor accompanied by the Lords Commissioners, has read out the Letters patent for the bill. The Clerk of the Crown reads out the short title of the bill and the Clerk of the Parliament responds by saying "La Reyne le veult" towards the House of Commons at the bar of the House for each bill. The phrase is also written on the paper of the bill to show that the Monarch granted royal assent to the bill.
