Prince William has awarded an MBE to an 11-year-old girl who is believed to be the youngest ever recipient of the honour.

Carmela Chillery-Watson has been recognised in the King’s Birthday Honours for her services to charitable fundraising.

Carmela has a rare muscle-wasting condition, which affects just one in a million children across the world.

She was diagnosed with the condition at the age of three and has helped raise more than £400,000 for the charity Muscular Dystrophy UK by doing around 25 fundraising and awareness campaigns.

Speaking after the ceremony at Windsor Castle, Carmela said she was left “speechless” after opening the letter informing her of the news.

The 11-year-old said: “I never would have thought that I would have got an MBE, I just wanted to do what I did to change communities.

“But this is absolutely incredible.

“I just never would have thought this would have happened in a million years.”

The Government believes Carmela is the youngest-ever MBE, but it does not hold all the historical data to confirm it.

The 11-year-old said the Prince of Wales was “very nice” and said she talked about her charity work and the money she raised.

Carmela was one of a number of individuals receiving MBEs, including Adjoa Andoh, who was celebrated for her portrayal of Lady Danbury in Netflix’s period drama Bridgerton.

The 62-year-old actress, writer and director received the honour in recognition of her services to drama over a four-decade career.
