Ken Livingstone

I undertake that, in the exercise of my functions of that office I will have regard to any guidance with respect to ethical standards issued by the secretary of state under Section 66 of the Greater London Authority Act 1999.

I don't think even when you find a person, you can be completely honest, ever. There's still pieces of you that you don't give away. I do believe you always need that place where it's just you, your thoughts, no one else's judgment or anything.
