by itself". Autonomy referendum and negotiation In March 2016 President Zaia announced that he had written to Prime Minister Matteo Renzi in order to start the negotiation both on the organisation of the referendum on autonomy and the devolution of further powers to Veneto according to article 116 of the Constitution. Zaia proposed the referendum to be held on the very same day of the 2016 constitutional referendum (which would reduce the regions' powers—article 117, while expanding the powers that can be devolved to regions according to article 116 and creating a regionalised Senate), a notion deemed legally impossible by undersecretary Gianclaudio Bressa, and the negotiation started in May. According to an opinion poll taken in June, 78.5% of Venetians would take part to the autonomy referendum, 78.4% would vote yes, 3.5% no and 18.1% did not know. According to the same poll, 70.7% of voters would participate also in the constitutional referendum, 41.3% would vote yes, 22.2% no and 36.5% did not know. Contextually, two bills calling for an independence referendum were introduced in the Regional Council, one by Liga Veneta's Marino Finozzi, Gabriele Michieletto, Alessandro Montagnoli and Luciano Sandonà, with the support of Roberto Ciambetti (President of the Council), and the other by Antonio Guadagnini. In April 2017 Zaia announced that the autonomy referendum would take place on 22 October, along with a similar referendum in Lombardy. 57.2% of Venetians participated in the referendum and 98.1% voted "yes". Consequently, President of Veneto Luca Zaia started a negotiation with the Italian government.

In November 2009 the Corriere del Veneto, the regional edition of the Corriere della Sera in Veneto, published a broad overview of what it described as "Venetist galaxy". The newspaper counted around 20 notable Venetist organisations: along the four major Venetist parties of the time (Liga Veneta–Lega Nord, Liga Veneta Repubblica, North-East Project and Venetian National Party), a large
