The 2018 Queen's Young Leaders are finding solutions to global issues such as climate change, food scarcity, gender-based violence, mental health, and access to education.
Dr Astrid Bonfield CBE, chief executive of The Queen Elizabeth Diamond Jubilee Trust which is a partner of the awards, congratulated this year's award recipients.
"Through selfless determination, the Queen's Young Leaders of 2018 are dedicating their lives to bring positive change to those around them.
"Their visit to the UK this June provides them with a unique opportunity to connect with each other and gain valuable lessons from experts and leaders from all walks of life."
The Queen's Young Leaders programme was established in 2014 by the Queen Elizabeth Diamond Jubilee Trust in partnership with Comic Relief, the Royal Commonwealth Society and the University of Cambridge's Institute of Continuing Education, in recognition of the Queen's lifetime of service to the Commonwealth.
