Abuja, FCT – In a stunning development that has sent ripples through Nigeria's political and security establishments, Minister of Defence Alhaji Mohammed Badaru Abubakar has tendered his resignation to President Bola Ahmed Tinubu, effective immediately, citing health concerns as the primary reason.

The announcement, confirmed late Monday by Bayo Onanuga, Special Adviser to the President on Information and Strategy, comes at a precarious moment for the West African nation.

Just hours earlier, President Tinubu had declared a national security emergency in response to escalating threats of terrorism, kidnappings, and banditry across multiple regions.

Abubakar's departure leaves a critical vacancy at the helm of the Ministry of Defence as the government prepares to unveil details of its emergency measures.

In his resignation letter dated December 1 and addressed directly to President Tinubu, the 63-year-old Abubakar expressed regret over his decision but emphasized the necessity due to deteriorating health.

President Tinubu swiftly accepted the resignation, issuing a statement through Onanuga praising Abubakar's "invaluable contributions to national security and his exemplary service to the federation."

The President is expected to nominate a successor to the Senate for confirmation later this week, potentially signaling a swift cabinet reshuffle to bolster the administration's security apparatus.

Abubakar, a prominent figure in the All Progressives Congress (APC), brings a wealth of experience to his brief tenure as minister. Elected governor of Jigawa State in 2015, he secured a second term in 2019, overseeing infrastructure projects and agricultural reforms that earned him national acclaim.

Appointed Minister of Defence on August 21, 2023, shortly after Tinubu's inauguration, Abubakar played a key role in coordinating military operations against Boko Haram insurgents in the northeast and bandit groups in the northwest.

His leadership came under scrutiny amid persistent security challenges, including a recent uptick in attacks that prompted Tinubu's emergency declaration.

The resignation's proximity to Tinubu's security emergency has fueled speculation.

Abubakar's letter comes hours after a high-level meeting at Aso Rock between President Tinubu and retired Chief of Defence Staff General Christopher Musa, where discussions reportedly centered on bolstering cross-border security amid rising threats.

Military sources, speaking anonymously, described the timing as "unfortunate but not unforeseen," pointing to Abubakar's visible fatigue during recent operations briefings.

Opposition voices, including those from the Peoples Democratic Party (PDP), have seized on the news to criticize the administration's handling of security.

Nigeria has grappled with multifaceted security threats for over a decade, from Islamist insurgencies in the northeast to farmer-herder clashes in the Middle Belt and kidnappings in the northwest.

Under Abubakar's watch, the military intensified drone surveillance and joint task forces, but incidents like the recent Kogi church abduction and thwarted attacks in Chibok underscore ongoing vulnerabilities.

As the nation awaits Tinubu's elaboration on the security emergency, the minister's exit could accelerate reforms.
