But first, let's meet the 5 young leaders:
Kumba Musa (27)Sierra Leone
'The reaction from the day we launched has been phenomenal, I had schools calling me and asking us to go and speak to their pupils and parents asking us to speak to their children. Just over a year later we now have 58 women on the team. We are giving science a new face. We are breaking the stereotype that it is a male-dominated field and showing that women can do it too.
I am most looking forward to learning from the other young leaders about their projects, how they work with their teams and the impact they have in their communities. I always ask them ‘What are you doing? Why did you do it? How are you doing it?’ Because when I listen to how they do whatever they are doing, even though it might be very different to my work, I can learn something from them. It also makes you feel ‘I am not alone’. We are all doing something to help our community.'
Abrahim Simmonds (22)Jamaica
'It has often been difficult for me to sell the idea of our work, because it is about arts and culture. So I hope that this platform will strengthen our organisation and people will take our work more seriously and value the arts and culture for young people in Jamaica.
The Arts is how we express ourselves and if we have to constantly borrow from other cultures to determine how we sing and dance, it robs us of the opportunity to feel a part of the country. Embracing our own arts and culture empowers us to want to contribute to the development of our country.'
Usman Ali (24)United Kingdom
'It is an honour and a privilege to be selected as the first Scot to be chosen for this award. There is a great amount of support to help us to improve our skills and abilities as we travel along on our leadership journey.'
Madeleine Buchner (24)Australia
'This isn’t really an award for me. It’s an award for every young carer who is doing this work. It’s an award for everyone who has turned something bad in their lives into something good. I grew up as a young carer and it shows that the bad days can be turned into something positive. I hope that I can use the Queen’s Young Leaders Award to educate people about young carers around the world.'
Senel Wanniarachchi (24)Sri Lanka
'My parents were so excited when I told them the news about becoming a Queen’s Young Leader. They were really proud of me and my mother called all of her sisters straight away to tell them the news. Growing up, I think I saw different perspectives of society through my parents’ work, so in a way both of them influenced the work I am now doing.'
The Queen's Young Leaders are arriving at Buckingham Palace to receive medals from Her Majesty The Queen in recognition of the work they have done in their local communities.
You can watch the live stream of the ceremony in the UK and around the world as The Queen and Prince Harry host the ceremony from 6:30pm (BST) below.
Launched in 2014, Queen's Young Leaders are a group of young people from all over The Commonwealth, who have shown exceptional leadership qualities. All winners have created initiatives to tackle problems in their communities.
