On Wunmi Mosaku’s first day in Ghana she was carrying a small but significant piece of her family’s heritage along with her.

Although the Bafta-winning actor was born in Nigeria, her visit to Ghana was an important one: it was a country which played a pivotal role in her family's history, and shaped the course of her own future.

So, as she arrived in Ghana for the first time earlier this year, the 32-year-old Luther star wore the dress that has become a treasured family heirloom – a dress that has come to represent the struggles women and girls face when trying to access education.

“In Nigeria, my grandma sold everything – everything – for my mum’s education. And my mum hid this one dress, it was my grandma’s favourite, and my mum wouldn’t let her sell it.”

This “hidden dress” has become symbolic of the sacrifices Mosaku’s grandmother made to send her children to school – sacrifices which included leaving them behind.
