King Charles is hosting the first Nigerian state visit to the UK for 37 years, with President Bola Ahmed Tinubu and his wife Oluremi Tinubu receiving a ceremonial welcome at Windsor Castle. At the start of the two-day visit, the leaders of the African nation with the biggest population - triple that of the UK - were greeted by senior royals including Queen Camilla, and the Prince and Princess of Wales. The King and President Tinubu will give speeches on Wednesday evening at the state banquet, which will be attended by political leaders and celebrities with links to Nigeria. However, there will be no traditional lunch with the King at Windsor as the president is a Muslim and fasting for Ramadan. In warm spring sunshine, the president and first lady - wearing traditional robes - were given the ceremonial grandeur of a royal welcome, including a carriage procession and a military band performance. Official gifts were exchanged, and discussions are aimed at enhancing business links, particularly in financial services. This historic visit underscores the importance of UK-Nigeria relations amidst current challenges and opportunities for economic reform and cooperation.
