The concern of this book is with how agents develop negotiations on specific policy issues. As outlined earlier, these negotiations take place within a 'governance regime', shown in Figure 1.1, the priorities of which have changed in Britain after the election of the Labour government in 1997. Within this changed governance regime new policy initiatives have been developed by government to which each agent has had to respond. We develop in this chapter the negotiation model used in our case studies. Our approach encompasses pluralism, state-led corporatism, resource-dependence, social class and institutional models and does not presume that any one dominates.
