The Italian Constitution prescribes that both chambers must accept every modification to the constitution twice within three months, and, if it passes with less than two thirds of the votes at the second scrutiny, a national referendum on the modification can be held (the reform will make it always possible to call such a referendum). Since the centre-left opposition opposed to the new constitutional reform, describing it as "dangerous", "separatist", and "antidemocratic", the first procedural step, that is, the approval by the Chamber of Deputies, was done successfully in October 2004, but with less than ⅔ of the lower-house votes, making possible the confirmative referendum. The second favourable polling, in Senate, was done in March 2005, whereas the third one occurred on October 20. During the third polling, former UDC leader Marco Follini announced he would abstain from the final vote, not support anymore the constitutional reform, followed by his party fellow Bruno Tabacci.
