King Charles III and Queen Camilla will host Nigeria's president in the country's first state visit to the UK in 37 years, Buckingham Palace has announced.

Bola Tinubu and First Lady Oluremi Tinubu have accepted an invitation to be guests of the King at Windsor Castle from 18 to 19 March.

State visits are considered a form of soft-power diplomacy, using the pomp of royal hospitality to strengthen relations with important international partners.

The last Nigerian state visit to the UK took place in 1989, when military ruler Gen Ibrahim Babangida travelled to meet the late Queen Elizabeth II for a four-day trip.

Although this will be Tinubu's first formal state visit to the UK, he has already met the King since taking office following Nigeria's disputed election in 2023.

Tinubu and his wife were received at Buckingham Palace in September 2024 and also held a bilateral meeting with the King on the sidelines of the COP28 summit in Dubai.

But a state visit allows for ceremonial pageantry aimed at elevating the occasion and demonstrating the importance with which the UK views those visiting.

The visit comes at a time of improving diplomatic and economic links between the UK and Nigeria - with trade between the two worth more than £8bn in the year to October, government figures show. This makes the African nation one of the UK's most important partners in the continent.

In 2024, the two countries signed a new trade and investment partnership designed to expand opportunities for business.

The agenda for the March visit has not been disclosed, nor details of the events planned for it - but state visits typically include carriage processions and a state banquet, and usually coincide with visiting leaders having political meetings.

In 2025 alone, the King presided over three state visits - those of French President Emmanuel Macron, US President Donald Trump and German President Frank-Walter Steinmeier - the first time the UK had held such a number in a single year since 1988.

The King has longstanding ties to Nigeria, a Commonwealth country, having expressed a love for Pidgin English and Nigerian Afrobeats music.

Before coming monarch, he visited the country four times as the Prince of Wales - in 1990, 1999, 2006 and 2018. Camilla, then the Duchess of Cornwall, joined him on the latter trip.

In 2023, the King's Trust International - formerly the Prince's Trust - officially launched in Nigeria, announcing a project aimed at tackling youth unemployment.
