Brookes, who was culled by the BBC to make way for the new generation of DJs, has been chosen as a key member of Hague's Creative Forum, the think-tank charged with rebranding the party for the millennium.
The forum, which will advise on everything from the party logo to its "new millennial brand image", meets for the first time next week. Other members include the fashion designer Katharine Hamnett and James Bethell, the man behind London's Ministry of Sound nightclub.
Tony Blair has made great political capital out of attracting celebrity support for his "Cool Britannia" message, and the recruitment of so-called "Trendy Tories" is further evidence that Mr Hague is not prepared to cede that ground.
Brookes, 37, boasts of being a millionaire and runs a growing media company that syndicates his shows to local radio such as Aire FM. Colleagues at the Leeds-based station said the move came as no surprise since "everyone knows Bruno is a Trendy Tory".
