'Inspiring, determined, kind': Who are these London schoolgirls describing?
As the US first lady spends her final days at the White House, schoolgirls thousands of miles away in London have been reflecting on the impact she has had on their lives.
Michelle Obama gave an inspiring speech at The Mulberry School for Girls in 2015, and then met the girls again in Washington five months later.
Four of them have described the effect her visit - and her motivational message - has had on them.
