In 2016, the Partito Democratico-led (PD) coalition government proposed a series of constitutional reforms with the aim of reducing the total number of parliamentarians, simplifying the legislative process, limiting the operating costs of the institutions, the disestablishment of the National Council for Economics and Labour (CNEL), and removing the perfect bicameralism in particular by greatly reducing the size and scope of the Senate. The proposal was rejected by 59% of voters through a constitutional referendum, prompting the resignation of the Prime Minister, Matteo Renzi.
