Question: Are the political parties that took part in the April 1999 election still active? Passage:Following the death of military dictator and de facto ruler of Nigeria, General Sani Abacha in 1998, his successor General Abdusalami Abubakar initiated the transition which heralded Nigeria's return to democratic rule in 1999. The ban on political activities was lifted, and political prisoners were released from detention facilities. The constitution was styled after the ill-fated Second Republic — which saw the Westminster system of government jettisoned for an American Presidential system. Political parties were formed (People's Democratic Party (PDP), All Nigeria Peoples Party (ANPP), and Alliance for Democracy (AD)), and elections were set for April 1999. In the widely monitored 1999 election, former military ruler Olusegun Obasanjo was elected on the PDP platform. On 29 May 1999, Obasanjo was sworn in as President and Commander-in-Chief of the Federal Republic of Nigeria.
