Royal assent is sometimes associated with elaborate ceremonies. In the United Kingdom, for instance, the sovereign may appear personally in the House of Lords or may appoint Lords Commissioners, who announce that royal assent has been granted at a ceremony held at the Palace of Westminster. However, royal assent is usually granted less ceremonially by letters patent. In other nations, such as Australia, the governor-general merely signs the bill. In Canada, the governor general may give assent either in person at a ceremony held in the Senate or by a written declaration notifying parliament of his or her agreement to the bill.

With what method is royal assent generally granted?
letters patent
