This chapter examines the institutional arrangements for integrity established in Peru at both the central and regional levels. First, it analyses the High-level Commission against Corruption (Comisión de Alto Nivel Anticorrupción, or CAN), the body officially mandated to guide the public integrity system. The analysis focuses on the Commission s capacity to fulfil its mandate, its independence from political interference, the availability of specialised and trained staff, and the adequacy of the resources and powers at its disposal. Second, this chapter looks more specifically at the core mandate of the CAN, which is to promote horizontal co-ordination between the different institutions of the public integrity system. Lastly, the chapter assesses the regional outreach and vertical co-ordination mechanisms of integrity policies that are in place, with a special focus on institutional capacities at the regional level.
