Since arriving in Warrington in March 2007, David has been involved in a wide range of activities. Working with a group of businessmen he saved Warrington Town Football Club and subsequently became a Director. He has also led fundraising initiatives for Warrington based charities, St Rocco's and Families United.

Since being elected to Parliament, David has continually argued for a reform to the unfair Barnett formula, which takes money away from the English regions and sends it to Scotland instead. He has also been at the forefront of the campaign for High Speed Rail.

David regularly contributes to Parliamentary debates on Energy Policy, Economic Growth & Job Creation and Banking. In July 2011, David was appointed to the select committee reviewing the draft Financial Services Bill, which will overhaul the UK banking and financial services industries.
