The programme of literary events has been announced for the Borders Book Festival to be held in Melrose in June.
Among those taking part are broadcasters Sir David Frost and Jeremy Vine who will talk about their work.
Others scheduled to appear are Rory Bremner, prizewinning historical writer Hilary Mantel, and author of the Horrid Henry children's books Francesca Simon.
This year's festival runs from 14 to 17 June at the Harmony House Gardens in Melrose.
Other authors taking part include William Boyd, Andrew Miller and Patrick Gale who will speak about their new books.
Andy McNab will launch his new thriller, James Holland will describe the exploits of the Dam Busters, and adventurer Mark Beaumont returns to the festival to speak about the Transatlantic rowing expedition that was nearly his last.
Also taking part is Peter Higgs, discoverer of the Higgs boson particle.
Festival director Alistair Moffat said he believed the programme was the "best yet" and the secret of its success was to try to be different every year.
"This year we have 34 authors new to Melrose: two of Britain's very greatest novelists, a visionary television programme maker and inventor of entire genres, two of our best known politicians and two of Britain's most gifted radio broadcaster," he said.
"And not only do we have wonderful guests, we have also assembled the best interviewing team imaginable: Kirsty Wark, Sally Magnusson, Rory Bremner and Jim Naughtie.
"And there is much, much more to delight us all this summer in Melrose."
