Chair of judges Peter Stothard said: "Goodness, madness and bewildering urban change are among the themes of this year’s longlist. In an extraordinary year for fiction the Man Booker Dozen proves the grip that the novel has on our world.
"We did not set out to reject the old guard but, after a year of sustained critical argument by a demanding panel of judges, the new has come powering through.”
The judges this year are academic and literary critic Dinah Birch; historian, writer and broadcaster Amanda Foreman; actor Dan Stevens, and academic, writer and reviewer Bharat Tandon.
The shortlist will be announced on 11 September, with the winner to be revealed at a ceremony at London's Guildhall on 16 October.
