Attempted to rule again in 2012
Bio in 2005 officially became a member of the Sierra Leone People’s Party (SLPP). That same year, he ran for the leadership of the SLPP at its national convention in Makeni but came in third. In July 2011 Bio was elected as the SLPP’s presidential flag bearer for the 2012 elections. He faced off with Ernest Bai Koroma of the ruling APC and was defeated after winning 37% of the votes. Bio did not give up; he became an active force within the SLPP and subsequently made the party a force to reckon with. In September 2017 the party elected him to lead them as the flag bearer in the 2018 presidential election, which he eventually won.
