President Olusegun Obasanjo permitted the transfer of Charles Taylor—who had been living in exile in the Nigerian coastal town of Calobar—to Sierra Leone for prosecution. Two days later, Taylor attempted to flee Nigeria, but he was apprehended by Nigerian authorities and transferred to Freetown under UN guard. Koroma's government (2007–2018) In August 2007, Sierra Leone held presidential and parliamentary elections. They had a good turnout and were initially judged by official observers to be "free, fair and credible". However, no presidential candidate won the 50% plus one vote majority stipulated in the constitution on the first round of voting. A run-off election was held in September 2007, and Ernest Bai Koroma, the candidate of the APC, was elected president and sworn in the same day. In his inauguration address at the national stadium in Freetown, President Koroma promised to fight corruption and the mismanagement of the country's resources. By 2007, there had been an increase in the number of drug cartels, many from Colombia, using Sierra Leone as a base to ship drugs to Europe. It was feared that this might lead to increased corruption and violence and turn the country, like neighbouring Guinea-Bissau, into a narco state. President Koroma quickly amended the existing legislation against drug trafficking—inherited at independence in 1961—to address the international concerns, increasing punishment for offenders in terms of prohibitive fines, lengthier prison terms, and provision for extradition of offenders wanted elsewhere, including the United States. In 2008, an aircraft carrying almost 700 kg of cocaine was caught at Freetown's airport and 19 people, including customs officials, were arrested, and the minister for transport was suspended. In 2014, the country was impacted by the 2014 Ebola virus epidemic in Sierra Leone. Julius Maada Bio presidency (2018-present) In 2018, Sierra Leone held a general election. President Koroma, who had served maximum two terms, was not able to seek re-election. The presidential election, in which neither candidate reached the required threshold of 55%, went to a second round of voting, in which Julius Maada Bio was elected with 51% of the vote against the candidate of ruling All People’s Congress (APC). On 4 April 2018, opposition candidate Julius Maada Bio of Sierra Leone People’s Party (SLPP), was sworn in as Sierra Leone’s new president.
