I have been privileged to serve my country and my party under your leadership.
However, for the remainder of the Parliament I want to be able to spend more time serving my constituents. My constituents have always come first for me, and they know the high standards and hard work that I ask of myself as the Member of Parliament for Norwich North.
As you know, I was only 27 when I was lucky enough to be elected as an MP, and of my four years in Parliament so far, I have spent three as a minister.
