However, most recent Prime Ministers' spouses have been involved in charities or community organisations, working to raise public awareness, funds, and support for a range of causes. They generally assist their partners in political campaigns, and participate in official duties that come with the position, such as hosting foreign dignitaries, and, in particular, entertaining the spouses of dignitaries; accompanying the Prime Ministers on national and international trips; attending conferences and functions; and speaking in public, particularly in the Prime Minister's constituency. They have attended the opening of Parliament; hosted visitors at The Lodge and Kirribilli House; visited Buckingham Palace, the White House, or the Japanese Imperial Palace; and been present at royal coronations and conferences.
