Lord Mandelson, the architect of New Labour dubbed the "Prince of Darkness" for his expertise in the dark arts of spin, has joined the political line-up at the Edinburgh International Book Festival.
He will discuss his memoir, The Third Man: Life At The Heart of New Labour with the Today programme presenter, James Naughtie, on 29 August.
The book festival's political offerings appear strong on leading figures from former governments, but thin on the ground when it comes to the new powers-that-be in Downing Street.
First Minister Alex Salmond chairs an appearance by the Tories' elder statesman Douglas Hurd, and Gordon Brown came to see the Poet Laureate, Carol Ann Duffy, on a private visit with his children.
UK Culture Secretary Jeremy Hunt is expected to attend, but not appear in an event.
