Decentralization was among Toledo's most successful institutional reforms. In addition to announcing regional elections upon his inauguration, he charged a Decentralization and Regionalization Commission with developing proposals. In 2002, a constitutional amendment was approved which established three levels of government: local, regional, and national. Over the next few years, the congress gradually passed on resources and responsibilities to the regional and municipal governments including food programs, social development projects, and health and education programs. He divided the single district up, called for regional elections, and eliminated the centralist Ministry of the Presidency that had been instituted under Fujimori. However, when Peru Possible's rival political party APRA made significant gains in regional elections, the Toledo administration halted its decentralization program by withholding power in the areas of revenue and expenditure. This left many regionally elected governors confused as to how far their authority extended. Without strong fiscal plans to support his new policy of centralization, Toledo had to continue decentralizing power and recognizing more regions. Toledo continued to assert control of regional governments, however, by withholding funding.
