The vice presidential debate was held on 14 December 2018, at the Transcorp Hilton Hotels in Abuja. All invited vice presidential candidates were present, with candidates discussing health, education, security, economy and foreign affairs policies plans. The presidential debate occurred on 19 January 2019, and took place at the same venue. The two leading presidential contestants were absent, with Atiku Abubakar leaving the venue upon discovering that Muhammadu Buhari was absent. Fela Durotoye (ANN), Oby Ezekwesili (ACPN) and Kingsley Moghalu (YPN) continued the debate, while criticising the absence of the others. Mark Eddo moderated the debate. Immediately following the elections there were claims of widespread fraud by the opposition. The claims included accusations of ballot box snatching, vote-trading and impersonation. There were also claims that caches of explosives were found by police. Losing candidate Atiku Abubakar filed a case in the Nigerian supreme court citing widespread irregularities in the polls . However the court dismissed his case, saying that Atiku has failed to prove widespread fraud committed by the electoral team of Buhari. The court also dismissed an allegation which said that Buhari lied about his academic background. The African Union said the elections were "largely peaceful and conducive for the conducting of credible elections." The electoral commission also described the elections as mostly peaceful. On the contrary, US based organisation freedom house severely criticised the conduct,saying that they were marred by irregularities and intimidation. The results of the presidential election were announced in the early hours of 27 February 2019. Senate President Bukola Saraki (PDP) was defeated in Kwara Central by the APC candidate. Currently, 64 incumbent Senators will not be returning as members of the Ninth Senate, having been defeated during the elections. While the APC will have a simple majority of votes in the Senate, it will not have a supermajority (74 votes), meaning it cannot push through constitutional amendments on its own. Three Senate seats have yet to be filled. On 2 March 2019, elections were held for governors of 29 of the 36 states of Nigeria. Elections were suspended on the original date in Rivers State. They were later held on April 3, where the INEC declared that incumbent Wike won re-election.
