The statement read, “During his time as our Patron, The King has been instrumental in bringing us closer to a world where everyone, everywhere, has clean water, decent toilets and good hygiene.”

“His Majesty has supported us in many ways since 1991 - from visiting countries including Ghana, Tanzania and Uganda to see how clean water changes lives, to attending Glastonbury Festival, and stopping by our award-winning garden at the RHS Chelsea Flower Show,” it continued.

WaterAid further expressed gratitude, “We are deeply honoured that His Majesty will host the Water and Climate Reception at Buckingham Palace tonight, bringing together young leaders and decision-makers to drive attention and action on climate change and water.”

Moreover, Charles is set to reunite with Prince William and Kate Middleton for St. Patrick's Day service on March 17.
