He also said he has submitted his resignation letter to the ward chairman of the party in his home State of Anambra.
The former PDP spokesman said he decided to resign from party politics because he believes he will contribute more to democracy and good governance in Nigeria by being non-partisan.
Metuh was the longest-serving elected member of the National Working Committee (NWC) of the PDP, and won election to serve in several national positions at six consecutive national conventions of the Party.
According to the letter, titled “Resignation From The PDP”, Metuh said, “During my three weeks trip for medical and personal reasons, I came to the realization that I can no longer play partisan politics in Nigeria. The reason for this decision is that from my experience and the nature of politics and development in Nigeria, I believe that I will contribute more to Democracy and good governance in Nigeria by being non-partisan. Being Non-Partisan gives me the status to work for the strategic interest and well-being of the Nigerian people without the hinderance of partisanship.
