Peter Gregory Obi CON (Igbo: [òbí] ⓘ; born 19 July 1961) is a Nigerian politician and businessman who was the Governor of Anambra State under President Olusegun Obasanjo from 17 March 2006 to 3 November 2006, when he was impeached.

Obi successfully challenged this outcome in court and was declared the duly elected candidate, becoming the governor of the state on 17 March, 2006.

Obi successfully ran for re-election and subsequently held the governorship till 17 March, 2014 when he handed over to his successor, Willie Obiano.

Obi sought the Nigerian vice presidential nomination in 2019, along Atiku Abubakar after decamping to Peoples Democratic Party but lost to Muhammadu Buhari.

Obi was born on 19 July 1961, in Onitsha, Anambra State, Nigeria, to a devout Christian family[1][2] from the Igbo town of Agulu.

After refusal of participating in the election in April 2007, which would later be won by Andy Uba, Obi challenged the impeachment, which was annulled by the Supreme court of Nigeria.

On 7 February 2010, Obi won the Anambra State election, and served his second term until 17 March 2014, when he was succeeded by Willie Obiano.

[9] Obi's business background and status as a major candidate unaffiliated with either of Nigeria's two main parties has drawn comparisons with Emmanuel Macron's successful 2017 French presidential election.

"[17] With his core message of prudence and accountability, Obi has managed to gain the backing of voters for his previously largely unknown Labour Party into a strong third force against two political heavyweights, APC and PDP.

[18] Before campaigns were officially kicked off, Obi's supporters held a series of One Million Man Marches in several Nigerian cities including Makurdi, Calabar, Lafia, Port Harcourt, Afikpo, Owerri, Enugu, Auchi, Abuja, Kano, Ilorin, Abakaliki and Ibadan.

On 8 July 2022, Obi unveiled his running mate, Senator for Kaduna North Senatorial District Yusuf Datti Baba-Ahmed.

So, I have the honour today to present to you, God willing, Nigeria's next vice president in the person of Senator Yusuf Datti Baba-Ahmed.

[28][29] As a result of the Pandora Papers leaks, the Premium Times reported on Obi's involvement in offshore companies in tax havens such as the British Virgin Islands and Barbados.

A Premium Times report claimed that Obi remained as director of Next International (UK) Limited while serving as Governor of Anambra State, which is in direct violation of Code of Conduct Bureau and Tribunal Act.

[32] The report also claimed that Obi's non-declaration of his offshore companies broke the Nigerian Constitution's provision that require public officers to declare all their properties, assets, and liabilities.
