Between David Cameron himself and the mass of Britain's individual voters lie a mass of intermediate institutions - charities, interest groups, think tanks, media outlets, and so forth. Some Shadow Ministers were assiduous during the last Parliament in building and maintaining relationships with interest groups. Iain Duncan Smith's Centre for Social Justice slowly did the same with a swathe of smaller, non-establishment charities and voluntary groups. However, Team Cameron built no organised structure during the last Parliament for building and maintaining relationships with key opinion formers - an omission which would raise eyebrows among America's professional campaigners. When the credit crunch bit at the end of 2008 the External Relations unit was shut down. It will be particularly important for a new Conservative Government to keep campaigning groups such as the Taxpayers' Alliance informed and, when possible, onside.
