In 1906 Georgios Theotokis introduced two reforms that aimed to improve the electoral system.

He established the prefecture as the constituency for the election of deputies. The expansion of the constituency (the 'wide' constituency) was intended to restrict the old patron-client relationship between the candidate and his constituents, facilitated by smaller constituencies. At the same time the institution of the voting booklet (1907) was introduced in the larger municipalities, a measure intended to prevent double voting.
