Party primaries were scheduled for between 4 April and 9 June 2022 with the Labour Party nominating Otti on 9 June.[4] For the All Progressives Congress, two separate parallel primaries were held on 26 May with one primary nominating economist Ikechi Emenike and the other primary picking former minister Uche Ogah.[5][6] INEC initially recognised Emenike as the legitimate nominee in July after a court ruled in his favour but switched recognition to Ogah after his successful November appeal;[7][8] however, the next month a new court ruling reinstated Emenike as the APC nominee.[9] The All Progressives Grand Alliance nominated educationist Gregory Ibe on 29 May;[10] however, a Federal High Court ruling nullified the primary on 1 December due to irregularities in the primary with a February Court of Appeal ruling barring the party from fielding a nominee.[11][12] The Peoples Democratic Party nominated professor Uche Ikonne on 25 May but Ikonne died in January 2023, prompting a new primary on 4 February which resulted in the nomination of Ahiwe.[13][14][15][16]
