Douglas Stuart has won the Booker Prize for his debut novel Shuggie Bain.
This year’s judges unanimously chose the Scottish writer to win the award.
The 44-year-old was announced as the winner of the prize in a virtual ceremony which featured contributions from former US president Barack Obama and the Duchess of Cornwall.
Shuggie Bain, which is based on Stuart’s childhood, is set in Glasgow in the 1980s and tells the story of a young boy growing up with a mother who is battling addiction.
The author explores poverty, tough upbringings and alcoholism in his book.
Margaret Busby, chair of the judging panel, described the novel as “daring, frightening and life-changing”.
She added: “The heart-wrenching story tells of the unconditional love between Agnes Bain – set on a descent into alcoholism by the tough circumstances life has dealt her – and her youngest son.
“Shuggie struggles with responsibilities beyond his years to save his mother from herself, at the same time as dealing with burgeoning feelings and questions about his own otherness.
“Gracefully and powerfully written, this is a novel that has impact because of its many emotional registers and its compassionately realised characters.
“The poetry in Douglas Stuart’s descriptions and the precision of his observations stand out: nothing is wasted.”
The shortlist for the £50,000 prize also featured Avni Doshi’s Burnt Sugar and Maaza Mengiste’s The Shadow King.
The New Wilderness by Diane Cook, Real Life by Brandon Taylor and Tsitsi Dangarembga’s This Mournable Body were also nominated.
Obama addressed the ceremony via a pre-recorded video message.
“I’ve always turned to writing to make sense of our world … and at their best Booker Prize-listed books remind me of fiction’s power to put ourselves in someone else’s shoes, understand their struggles, and imagine new ways to tackle complex problems and effect change,” he said.
“I want to salute the work of the Booker Prize Foundation to encourage people to read more fiction and promote the art of reading for the public benefit.”
The ceremony also saw the Duchess of Cornwall discuss the value of reading during the pandemic.
“While Covid deprived us of so many cultural pleasures − live music, theatre, cinema, art galleries, even being together in the flesh this evening − we have, at least, been able to read,” she said.
“And as long as we can read, we can travel, we can escape, we can explore, we can laugh, we can cry and we can grapple with life’s mysteries.
“For all these reasons, this year’s Booker Prize is even more important than usual.
“It celebrates wonderful writers who share their gifts to strengthen, provoke, move and comfort their readers.”
Stuart is the second Scottish writer to win the award after James Kelman scooped the 1994 prize for How Late It Was, How Late.
Busby was joined on the judging panel by writers Lee Child, Sameer Rahim and Lemn Sissay, as well as classicist Emily Wilson.
Last year’s prize was jointly won by Margaret Atwood’s The Testaments and Bernardine Evaristo’s Girl, Woman, Other.
The Booker Prize, first awarded in 1969, is open to writers of any nationality whose work is written in English and published in the UK or Ireland.
