I am proud of the many successful newspaper campaigns at the Sun and the News of the World under my editorship.
In particular, the 10-year fight for Sarah's Law is especially personal to me.
The battle for better protection of children from paedophiles and better rights for the families and the victims of these crimes defined my editorships.
Although these difficult times will continue for many months ahead, I want you to know that News International will pursue the facts with vigour and integrity.
I am aware of the speculation about my position. Therefore it is important you all know that as chief executive, I am determined to lead the company to ensure we do the right thing and resolve these serious issues.
We will face up to the mistakes and wrongdoing of the past and we will do our utmost to see that justice is done and those culpable will be punished.
