A highly personal film shot by artist Charlotte Prodger on her iPhone, which recalls her experiences of coming out as gay in rural Scotland, has won her the prestigious £25,000 Turner Prize.

The Glasgow-based artist, known for exploring queer identity, won the annual art award for two of her videos.

One of those, titled Bridgit, was filmed entirely on her phone and features her reading from her diaries.

Prodger said she was “quite overwhelmed” and “very touched” to win.

“The stories that I’m telling, although they’re mine and they’re personal, are stories that a lot of people – I guess queer people – have experienced,” she told BBC News.

The award caps a good year for the 44-year-old, who has also been chosen to represent Scotland at the 2019 Venice Biennale.

The judges said they “admired the painterly quality of Bridgit and the attention it paid to art history”.

Tate Britain director Alex Farquharson, who chaired the jury, said the winning artwork “seems to make a lot of points for a younger generation”.

He said: “It deals with gender as unfixed, as something fluid, as something not always conforming to society’s norms.”
