Stephen Fry has announced he is going to quit Twitter to concentrate on his work.

The 52-year-old writer, actor and comedian, who has more than one million followers on the social networking site, decided to say farewell to his fans to work on a new book.

However, he has promised to return to the micro-blogging world once he has completed a follow-up to his autobiography Moab Is My Washpot.

In a message to his fans, Kingdom star and QI presenter Stephen said: “This morning I switch off most of my connections with the outside world, for I have work to do. I must deliver a book to my publishers by the end of April or my soul and testicles will be forfeit.”

He wrote that he needs “absolute peace” and “zero distraction” to concentrate.

“All this is a way of saying, of course, that my Twitter stream will dry up for that period,” he said.

“Accept my apologies for what must be, and believe me, no one yearns more keenly for the day when I will be able to be back amongst you all.
