Prince Albert of Monaco's surprise appearance at Commonwealth Day service explained

In a post on X, Ms Botchwey said she was "delighted" to meet Prince Albert on Commonwealth Day and announced a partnership with FPA2, the Prince Albert II of Monaco Foundation, to strengthen ocean conservation through the Commonwealth Blue Charter Project Incubator.

She added that the initiative would help build "a sustainable future for all", providing the clearest explanation yet for the prince’s unexpected presence during one of the Commonwealth’s most high-profile annual events.

The Commonwealth Secretariat then confirmed the agreement in an official press release published on March 11.

It said the new partnership would accelerate ocean conservation for Commonwealth countries in Asia and the Pacific and would bring together scientists, political leaders and civil society figures in support of marine protection.

The Secretariat said the collaboration directly advances the goals of the Apia Commonwealth Ocean Declaration, which was unanimously adopted at the Commonwealth Heads of Government Meeting in Samoa in 2024.

Under the arrangement, the partnership will be implemented through the Commonwealth Blue Charter Project Incubator.

The scheme provides grants of up to £50,000 for early-stage projects in areas including marine pollution, ecosystem restoration, the blue economy, sustainable fisheries and the ocean-climate nexus.

According to the Commonwealth, the Prince Albert II of Monaco Foundation will target its support at projects in Asia and the Pacific, while the wider programme is designed to unlock further investment and strengthen local partnerships on the ground.

Prince Albert’s appearance had prompted surprise because Commonwealth Day is traditionally centred on the organisation’s 56 member states and their representatives.

The annual multi-faith service at Westminster Abbey on March 9 was attended by King Charles III and Queen Camilla, alongside senior royals, foreign ministers, High Commissioners, Prime Minister Sir Keir Starmer and more than 700 schoolchildren.

Almost 2,000 people from around the Commonwealth were present at the service, which formed the centrepiece of the day’s celebrations in London.

Monaco is not listed among the Commonwealth’s 56 member countries, making Prince Albert’s presence especially notable.

The Commonwealth describes itself as a voluntary association of 56 independent and equal countries, and its official member list includes nations across Africa, Asia, Europe, the Caribbean and the Pacific, but not the Principality of Monaco.

That meant Albert’s attendance stood out immediately, even before Ms Botchwey’s announcement shed light on the environmental agenda surrounding his visit.

This year’s Commonwealth Day theme was "Unlocking opportunities together for a prosperous Commonwealth".

In announcing the theme last month, Ms Botchwey said the occasion was meant to highlight how countries and communities can work together to improve lives across the 56-member organisation.

The Prince Albert II of Monaco Foundation, founded in 2006, is described by the Commonwealth as a global non-profit focused on biodiversity, climate, oceans and water resources.

In its announcement, the Secretariat said one-third of the world’s ocean under national jurisdiction lies within the Commonwealth, underlining why marine protection has become such a prominent part of the organisation’s international work.
