Reinfeldt became the Prime Minister of Sweden on 6 October 2006, serving concurrently as Leader of the Moderate Party. The 41-year old Reinfeldt became the youngest person to become Prime Minister since Rickard Sandler became Prime Minister at the age of 40 in 1925. With victories in 2006 and in 2010, Reinfeldt was the Moderate Party's longest-serving prime minister and the only person to lead the party to two consecutive general election victories. His Government compromised four parties (including his own) which prior to the election had formed a coalition named Alliance for Sweden, later turned into the Alliance.
