The King presented The Queen Elizabeth Prizes for Higher and Further Education in recognition of outstanding work at UK universities and colleges in a ceremony at St James's Palace.
The King presented awards to 19 universities and colleges who have been recognised for their innovation and excellence across a range of subject areas.
Recipients included a centre tackling sustainability in the textile industry, a partnership providing higher education in prisons, and groundbreaking research into Paralympic performance.
The Queen, The Princess Royal, and The Duke and Duchess of Gloucester joined the presentation ceremony.
The Princess Royal attended the ceremony in Her Royal Highness's capacity as Chancellor of The University of Edinburgh, which is receiving an award for research and education by its Centre for Fire Safety Engineering.
Following the presentations, Their Majesties and Their Royal Highnesses joined recipients at a reception to hear more about their award-winning work.
The Queen Elizabeth Prizes for Higher and Further Education are part of the UK national honours system.
First awarded in 1995 and now in their sixteenth round, the Prizes are granted every two years on the advice of the Prime Minister following a rigorous review process managed by the Royal Anniversary Trust, an independent charity.
