Sir Paul Stephenson resigns from his role as commissioner of the Metropolitan police but says his integrity remains intact:

"There are a great number of things I value as part of my professional life – very high in this list are my reputation for judgement and integrity.

"On judgement: running a large and overwhelmingly successful organisation like the Met must be dependent to a great extent on others providing the right information and assurances. I could reiterate that I had no reason to doubt the original investigation into phone hacking or be aware of the documents and information in our possession and only recently provided by News International. I could point to the many other successes of the Met. I could point to the long history of how and why the relationship between the Met and media has developed a way of doing business that has brought real benefits but perhaps runs the risk of misinterpretation or worse. In this particular regard it is clear to me that the current furore marks a point in time, a need to learn and change.

"However, as commissioner I carry ultimate responsibility for the position we find ourselves in. With hindsight, I wish we had judged some matters involved in this affair differently. I didn't and that's it.

"I do not believe this on its own would be a matter for me to consider my position as commissioner.

"However, the issue of my integrity is different. Let me state clearly, I and the people who know me know that my integrity is completely intact. I may wish we had done some things differently, but I will not lose sleep over my personal integrity."
