Papadopoulos, in a move which would bolster his own authority, deposed the king. On 1 June, a Constituent Act was proclaimed, which declared Greece a presidential republic, with Papadopoulos as president. The act was to be confirmed by a plebiscite, which was held on 29 July 1973. The defunct political parties and their leaders urged for a "No" as a sign of opposition to the regime, but the vote was tightly controlled by the junta, and the results were predictably favourable to the regime.
