The Prince of Wales will travel to the South of France this weekend to call for more to be done to protect the world's oceans.
In what his team describes as a "landmark speech" in Monaco on Sunday - World Oceans Day - he will address environmentalists and, crucially, investors, to urge them to work together to protect our oceans
Prince William will attend the Blue Economy and Finance Forum as founder of the Earthshot environmental prize which looks for solutions to the world's climate challenges.
The forum is the curtain-raiser to the UN Oceans Conference in Nice next week.
"The Prince of Wales feels passionately about action being taken to protect and restore our oceans," a Kensington Palace spokesperson told the BBC. "Tomorrow, he's going to be calling for swift, immediate global action. The time is now."
