Within hours the Royal Palace gates and enclosure were covered with flowers that people brought spontaneously. A viewing of the body was held at the Royal Palace in central Brussels; 500,000 people (5% of the population) came to pay their respects. Many waited in line up to 14 hours in sweltering heat to see their King one last time. Along with other members of European royalty, Queen Elizabeth II of the United Kingdom and the other Commonwealth realms attended the funeral (the only foreign state funeral ever attended by her in person as monarch). All European monarchs attended the service, as did Emperor Akihito of Japan. Non-royal guests included more than 20 presidents and leaders, such as UN Secretary General Boutros Boutros-Ghali, European Commission President Jacques Delors, French President François Mitterrand, Egyptian President Hosni Mubarak, German President Richard von Weizsacker, Polish President Lech Walesa, Bosnian President Alija Izetbegovic, Italian President Oscar Luigi Scalfaro, Canadian Governor General Ray Hnatyshyn and former American President Gerald Ford were also present at the funeral.
