Investigations into Central Europe’s emerging party–state relationships—in contrast to those of the former Soviet Union—have focused less on the abuse of public office for private gain and more on patronage and clientelism as political resources. That debate in turn has been bounded by the conventional political science preoccupation with civil society, party, and state relations. This article contends that these conventions have tended to deflect our attention from the contemporary dynamics of political corruption in Central Europe, in which the commercial sector is a major player and the gains of political players primarily private. Building on the assumption that party systemic adaptations are contingent on changing power relations within the political economy, this article offers an ideal typical party model to characterise the behaviour of political parties that preside over the continuous marketization of the state. A "corporate brokerage party" directs its strategic focus to the private sector and acts primarily as a broker of the state’s power in the marketplace, whether expressed through privatisation, regulation, or public procurement. Using the Czech Republic as a critical case study for Central Europe, the evidence suggests that politicians able to direct allocation to the private sector with low regulatory constraints act less evidently as technocratic brokers of the public interest, partisan constituency, or organisation builders and more as private agents.
