Nicholas Hytner: Exit Stage Left

“It’s been a joy and a privilege to lead the National Theatre for ten years and I’m looking forward to the next two. I have the most exciting and most fulfilling job in the English-speaking theatre; and after twelve years it will be time to give someone else a turn to enjoy the company of my stupendous colleagues, who together make the National what it is.” 

Nicholas Hytner announcing that he will step down as director of the National Theatre in 2015. 
Dominic Cavendish on his "great transformation".
And more - deservedly - fulsome praise from Michael Billington in The Guardian.
