Senator Aminu Waziri Tambuwal, representing Sokoto South Senatorial District, has resigned from the Peoples Democratic Party (PDP) and defected to the African Democratic Congress (ADC), citing deepening internal crises within the opposition party.
Tambuwal, a former governor of Sokoto State, disclosed this in a resignation letter dated March 11, 2026, addressed to the PDP ward chairman in Tambuwal/Shinfiri Ward of Tambuwal Local Government Area.
In the letter, which was made available to journalists on Thursday, the lawmaker said his decision followed extensive consultations with his political associates and supporters.
“After deep reflection and extensive consultations with my political associates and supporters, I have decided to resign my membership of the Peoples Democratic Party with immediate effect,” he stated.
Tambuwal explained that persistent internal disputes, leadership disagreements and widening divisions within the party had made it increasingly difficult for him to remain in the PDP.
“The persistent internal crises, leadership disagreements and growing divisions within the party have made it increasingly difficult for me to continue my membership,” he added.
Despite leaving the party, the former governor expressed appreciation to the PDP for the opportunities it provided him to serve the country in different capacities.
“I remain grateful to the party for the platform it provided me to serve Nigeria as Speaker of the House of Representatives and later as Governor of Sokoto State,” he said.
Tambuwal served as Speaker of Nigeria’s lower legislative chamber, the House of Representatives of Nigeria, between 2011 and 2015 before emerging governor of Sokoto State in 2015 under the All Progressives Congress (APC). He later defected to the PDP in the same year and was re-elected governor in 2019.
After completing his second term as governor in 2023, he was elected to the Senate to represent Sokoto South.
Confirming his latest political move, Tambuwal said he had joined the African Democratic Congress alongside his supporters and political allies, describing the decision as part of efforts to strengthen democratic values and offer Nigerians a credible political alternative.
“My decision is guided by the conviction that Nigeria requires a stronger political platform built on integrity, accountability, inclusiveness and a clear commitment to national development,” he said.
The development comes at a time when political alignments and realignments are beginning to intensify ahead of future elections in Nigeria.
