The Nigerian presidency confirmed that a defence MOU was among the agreements signed during President Tinubu’s visit to London. The document’s content does not appear in published UK Government records, and no Nigerian official has described its content. No legislative body was consulted. A sovereign security commitment was made in the name of 220 million Nigerians, without public documentation.

When President Bola Ahmed Tinubu arrived in London last week for a state visit (March 16–19, 2026), his office prepared Nigerians for a series of landmark agreements. In the days that followed, the announcements were substantial: a £746 million ports financing deal, a trade and investment communiqué, education partnerships, a dairy production MOU, and a fintech regulatory approval. The UK Government published detailed documentation for all of them within hours after each signing.
There was one exception.
Presidential spokesman Bayo Onanuga confirmed that among the agreements signed during the visit from March 16 to March 19, 2026, was a Memorandum of Understanding covering defence cooperation. It was named alongside trade, investment, and cultural cooperation as part of the visit’s outcomes.
Unlike all other agreements signed in London that week, the defence MOU received no mention in UK Government publications, press releases, or communiqués.
A thorough search of UK public records revealed no documentation of any defence agreement between the UK and Nigeria for the week of March 13–19, 2026.
The question that demands an answer is simple: what did Nigeria agree to?
What The Publication Record Shows — And Does Not Show
The UK Government was exhaustively transparent about every other element of the visit. The UKEF ports deal release ran to several hundred words, included CEO quotes from British Steel, Citi, and UKEF, named the Nigerian contractors involved, and specified the British content requirement in pounds.
The UK-Nigeria Enhanced Trade and Investment Partnership communiqué, signed March 16, ran to thousands of words across multiple annexes, naming individual companies, regulatory bodies, university partnerships, and fintech approvals.
Security forms a named priority in the UK-Nigeria Strategic Partnership, but the defence agreement from this visit has produced no public documentation.
While defence MOUs are often confidential, no Nigerian official has yet clarified what this cooperation covers.
In matters of national security, that distinction is not a bureaucratic detail. It is the substance of the agreement itself.
The Constitutional Question
Nigeria’s 1999 Constitution, as amended, grants the executive branch primary authority over foreign affairs and defence. But it also vests in the National Assembly the power to approve treaties and international agreements that carry legal obligations for the Federation. The precise boundary between an executive MOU and a treaty requiring legislative approval has long been a contested grey area in Nigerian constitutional practice.
The relevant question is whether the defence MOU signed in London falls under the category requiring legislative approval. Without knowing the contents, neither the legislature nor the Nigerian public can make that determination. Until that determination is possible, there may be limited ability to hold the executive to account for what was agreed.
TheDiggerNews now puts the following questions to the Office of the National Security Adviser, the Ministry of Defence, and the presidency, as Nigerians need to know:
What is the subject matter of the defence MOU signed in London during President Tinubu’s visit between March 16 and March 19, 2026?
Does it involve basing rights, equipment procurement, intelligence sharing, or operational cooperation?
Was the National Assembly or its relevant committees briefed before or after the signing?
Under what legal authority was the MOU signed, and does it bind the Nigerian state?
Will the text be published, and if not, on what grounds is it being withheld?
Context: Why This Matters Now
Nigeria is not navigating an ordinary period of security. The northeast insurgency, the northwest banditry crisis, the recent killings and abduction in the north-central, and the renewed agitation in the south have stretched the Nigerian military across multiple simultaneous theatres. Any external defence partnership — particularly one with a former colonial power that retains significant strategic interests in the region — carries implications that go beyond logistics or training exercises.
The UK, for its part, has been deepening its security footprint across West Africa in recent years, partly in response to the contraction of French influence following a series of coups in the Sahel.
A defence MOU with Nigeria — the region’s largest military and most populous state — is not a routine administrative exercise. It is a strategic alignment. Nigerians deserve to know, at a minimum, which broad alignment category their president has committed them to.
The UK Government’s own communiqué from the March 16 ministerial dialogue noted that the UK-Nigeria Strategic Partnership covers security as a named pillar. That framework exists. What was added to it on March 19 is the question.
What Next
TheDiggerNews will follow up on this by filing information requests with the UK Ministry of Defence and the Foreign, Commonwealth and Development Office, seeking any publicly releasable summary of the defence cooperation agreement signed in London during the week of March 13–19, 2026. We will continue to press the Nigerian presidency, the National Security Adviser’s office, and the Ministry of Defence for the text or a formal description of its scope.
The port financing deal, signed the same day, has a 400-page paper trail on the UK side alone, in contrast to the defence MOU, which currently has none. This contrast highlights the information available to Nigerians regarding the security commitments made during the visit.
At present, no information has been released.
