As Prince of Wales, Charles undertakes official duties on behalf of the Queen. He officiates at investitures and attends the funerals of foreign dignitaries. Prince Charles makes regular tours of Wales, fulfilling a week of engagements each summer, and attending important national occasions, such as opening the Senedd. The six trustees of the Royal Collection Trust meet three times a year under his chairmanship. Prince Charles travels abroad on behalf of the United Kingdom. Charles has been regarded as an effective advocate of the country. In 1983, Christopher John Lewis, who had fired a shot with a .22 rifle at the Queen in 1981, attempted to escape a psychiatric hospital in order to assassinate Charles, who was visiting New Zealand with Diana and William. While visiting Australia in January 1994, two shots from a starting pistol were fired at him on Australia Day by David Kang in protest of the treatment of several hundred Cambodian asylum seekers held in detention camps. In 1995, Charles became the first member of the royal family to visit the Republic of Ireland in an official capacity.
