Declaration of personal interests by the Mayor's Office. The 25 Members of the London Assembly and the Mayor of London are required to declare their personal interests in the Standing Register of Interests. Members must register these details with the GLA's Monitoring Officer within 28 days of the commencement of their term of office, and must submit an updated notification within 28 days of becoming aware of any change to their personal interests. This currently links to the existing pages on the GLA website where the information can be found. We are working on making this data available in an easier to use format.
