I am very happy for constituents to view my expenses incurred in my role as Member of Parliament for Witney. These are freely available to view online via the Independent Parliamentary Standards Authority (IPSA) website. You can view this here.
As an MP, I also have to keep an up to date Register of Interests. The main purpose of the Register is to provide information about any financial interest which a Member has, or any benefit which he or she receives, which others might reasonably consider to influence his or her actions or words as a Member of Parliament. You can view mine here.
