New elections in the autumn of 1848 returned a constitutional majority, but it ended by voting in favour of a constituent assembly. There was talk of instituting a central Italian kingdom with Leopold as king, to form part of a larger Italian federation, but in the meanwhile the grand-duke, alarmed at the revolutionary and republican agitations in Tuscany and encouraged by the success of the Austrian troops, was, according to Montanelli, negotiating with Field-Marshal Radetzky and with Pius IX, who had now abandoned his liberal tendencies, and fled to Gaeta. Leopold had left Florence for Siena, and eventually for Porto Santo Stefano, leaving a letter to Guerrazzi in which, on account of a protest from the pope, he declared that he could not agree to the proposed constituent assembly. The utmost confusion prevailed in Florence and other parts of Tuscany.
