Senator David Mark, a former Senate President, has officially resigned from the Peoples Democratic Party (PDP), citing unresolved internal divisions and ongoing leadership crises within the party.

In a resignation letter dated June 27, addressed to the PDP Chairman of his Otukpo Ward in Benue State, Mark expressed disappointment over the party’s current state, describing it as a shadow of its former self and vulnerable to public ridicule.

The letter stated, “I bring warm greetings to you and members of the Peoples Democratic Party (PDP), Otukpo Ward 1, and by extension, to the entire Benue State and Nigeria. I write to formally inform you of my decision to resign my membership of the party with immediate effect.”

Mark recalled his long-standing commitment to the PDP, noting that he remained loyal even when many stakeholders left following the party’s defeat in the 2015 presidential election. “I pledged to remain the last man standing,” he wrote.

He acknowledged his previous efforts to rebuild and reposition the PDP, which helped restore some national relevance.

However, he added, “Recent events marked by deepening divisions, persistent leadership crisis, and irreconcilable differences have reduced the party to a shadow of its former self, subjecting it to public ridicule.”

After consulting with family, friends, and political associates, Mark revealed his decision to join the National Coalition of Political Opposition Movement in Nigeria. He described this move as part of a collective effort to rescue the nation and safeguard democratic gains.

Earlier on Wednesday, The Guardian reported that Mark, alongside former Osun State Governor Rauf Aregbesola, has been appointed interim National Chairman and National Secretary, respectively, of the soon-to-be-launched African Democratic Congress (ADC) coalition platform.

This development signals a significant realignment ahead of the 2027 general elections as opposition leaders consolidate forces to challenge the ruling All Progressives Congress (APC).
