Former Senate President David Mark has officially resigned from the Peoples Democratic Party (PDP), bringing to an end his decades-long association with the party he helped found.

Mark, who played a key role in shaping the PDP since its inception, announced his resignation in a letter dated June 27.

The development follows his recent appointment as one of the interim leaders of the coalition-backed African Democratic Congress (ADC), a move that signals a shift in Nigeria’s evolving political landscape.

In his resignation letter addressed to the PDP leadership in Otukpo Ward 1, Benue State, Mark cited the party’s deep-seated leadership crisis and irreconcilable differences as the reasons behind his departure.

“The irreconcilable differences in the PDP have subjected the party to public ridicule and reduced it to a shadow of its former self,” he noted.

Reflecting on his loyalty and contributions to the PDP over the years, Mark said:

“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.

“You may recall that over the years, I have remained firm and deeply committed to the ideals of the PDP. Even when nearly all stakeholders departed the party following our loss in the 2015 presidential election, I pledged to remain the last man standing.
