In September 2008 Gül became the first Turkish leader to visit Armenia where, in meetings with President Serzh Sarkisian, the two leaders formulated a solution to the tendentious problem of the genocide question, sparking a major debate in Turkey, but both the Armenian and Turkish parliaments refused to ratify the agreement. In November 2011, President Gül led a state visit to the United Kingdom as a guest of Queen Elizabeth II. The President met political and business leaders, visited the Olympic Park and was guest of honour at a state banquet at Buckingham Palace.
