CIA Director George J. Tenet, dogged by controversies over a string of US intelligence setbacks, has decided to resign for personal reasons and will leave the agency in July, President Bush announced today.

"George Tenet is the kind of public servant you like to work with. He's strong, he's resolute, he's served his nation as the director for seven years. He's been a strong leader in the war on terror, and I will miss him."
