In 1992, the first constitutional elections were overseen by former United States President Jimmy Carter, and the People's Progressive Party led the country until 2015. The two parties are principally organised along ethnic lines and as a result often clash on issues related to the allocation of resources. In the General Elections held on 28 November 2011, the People's Progressive Party (PPP) retained a majority, and their presidential candidate Donald Ramotar was elected as president.
