Alphonsus Nwosu has resigned as a member of Peoples Democratic Party Board of Trustees.

Nwosu, in a January 12, 2023 letter addressed to Iyorchia Ayu (national chairman of the party) and Adolphus Wabara (acting chairman of the BoT), blamed his decision on the party's failures to respect its power rotation/zoning principle.

Nwosu served as the Minister of Health under the Ex-President Olusegun Obasanjo administration between 1999 to 2007. He stated that the PDP members must learn to respect the constitution and the agreements reached by the members of the party.

The letter read;

“I hereby resign my membership of the Peoples Democratic Party and its Board of Trustees with effect from today Thursday 12th January, 2023.

“This resignation for me is a matter of conscience and principle because of the Party’s inability to adhere to the rotation provision in its (PDP) constitution.

“The journey to rotational presidency between the North and South of Nigeria has been a long and arduous one and I have been involved.”
