From this article:
"Another former coalition minister with private sector ties is Mark Prisk, minister of state for housing and local government until last October, who now declares an income of between £15,000 and £20,000 a year from Essential Living, a private rental provider.
Requests for comment to Mitchell and Prisk were not returned by the time of publication. "
To be fair that's small fry for MP's second incomes and at least he only has two jobs compared to our PCC who has four!
