Bianca Odinakachukwu Olivia Odumegwu-Ojukwu (née Onoh, born 5 August 1968)^[1] is a Nigerian politician, diplomat, lawyer, businesswoman and beauty pageant titleholder. The widow of former Biafra president Chukwuemeka Odumegwu Ojukwu, ^[2][3] she is a multiple international pageant titleholder, having won Most Beautiful Girl in Nigeria, Miss Africa, and Miss Intercontinental. Formerly a presidential advisor,^[4][3] she was the country's ambassador to Ghana and became Nigeria's Ambassador to Spain in 2012.^[5]

In 1989, halfway through her reign as MBGN, Odumegwu-Ojukwu began a relationship with the former Biafran Head Of State Chukwuemeka Odumegwu Ojukwu, a political associate of her father's, over thirty years her senior.^[16] Their controversial romance was a national talking point in the early 1990s.^[17][18] The immense pressure of being under the public eye became increasingly unbearable, causing her to resign as Miss Intercontinental as her main concern was completing her education as a law student. In 1994,^[19] having finally obtained her degree, she married the former Biafran president in a lavish wedding ceremony held in Abuja.

In 2012, following the death of her husband, his will, which left most of his assets to her, generated a great deal of controversy and disaffection among several family members. Odumegwu-Ojukwu appealed to her critics to allow Ikemba Odumegwu-Ojukwu to "rest in peace", describing him as a man of honour and integrity whose legacy should not be obscured by rancour over inheritance issues and stating that the will was drafted in 2005, registered and placed in the custody of the State Probate Registry with the legal witnesses and executors, who were present at the time it was prepared, still living.^[20] In 2023,She won her legal battle over the Ojukwu Estate.

On 17 March 2022, during the inaugural ceremony of governor Chukwuma Soludo, Odumegwu-Ojukwu delivered what has now been widely dubbed a 'valedictory slap' to a visibly inebriated Ebelechukwu Obiano, the outgoing first lady of Anambra State, who had physically attacked her at the state function.^[21]

Odumegwu-Ojukwu was married to Ikemba Odumegwu-Ojukwu until his death in 2011; the couple had three children together. Of her marriage, she admits that while she was happy to have found her husband, she would not encourage her daughter to make a similar choice of marital engagement.^[22] Odumegwu-Ojukwu holds many traditional titles in her native land as well as the highest chieftaincy title conferred on women in her region.

Odumegwu-Ojukwu was honoured with the Certificate of Merit by El Mundo Diplomatico for her efforts towards providing effective platforms for constructive engagement between Nigeria and Spain, and was voted Africa's Outstanding Ambassador by Dutch magazine The Voice in 2014. She was also honored with the "Ambassador of Excellence" Award by the Government of Anambra State, Nigeria at its Silver Jubilee commemoration in 2016. She is a member of the Board of Trustees of the All Progressives Grand Alliance, the Political Party that was founded by her late husband Chukwuemeka Odumegwu-Ojukwu and which has maintained political power in Anambra State for over a decade. Her bid to represent her senatorial district in 2018 was stalled as a result of irregularities which occurred during her party's primary elections.^[23] She is presently the secretary of the Truth, Justice and Peace Commission set up in 2022 to investigate the root causes of violence, insecurity and separatist agitations in South Eastern Nigeria.
