Brazilian tribal leader among other guests at event with theme of repair, along with Ruth Jones and Nicola Sturgeon

The Edinburgh book festival is to champion the positive power of hope later this summer with events involving Hanif Kureishi, the Palestinian poet Najwan Darwish and an exiled Brazilian tribal leader.

The core theme for this year’s festival will be the “expansive” concept of repair, and offering solutions and optimism at a time of crisis and conflict, said Jenny Niven, the event’s director.

“I think it’s an act of hope,” Niven said. “Repair is a positive, optimistic approach, [and] looking at journalism, looking at politics, there are a lot of things that are broken – politically, mental health and wellbeing, societally.

“And rather than leaving people sort of worried, we’re hoping that we can present new writers and thinkers who offer solutions and new ideas and great analysis that moves the conversation forward.”
