Errani (–10.6% compared to 2005) and the Democrats (–7.7%) lost ground to the Five Star Movement, whose candidate won a surprising 7.0% of the vote, in what was the worst result for the centre-left in a regional election in Emilia–Romagna. The other surprise of the election was Lega Nord, which gained 13.7% of the vote, up from 4.8% in 2005.
The Legislative Assembly of Emilia-Romagna (Assemblea Legislativa dell'Emilia-Romagna) is composed of 50 members. 40 councillors are elected in provincial constituencies by proportional representation using the largest remainder method with a Droop quota and open lists, while 10 councillors (elected in bloc) come from a "regional list", including the President-elect. One seat is reserved for the candidate who comes second. If a coalition wins more than 50% of the total seats in the Council with PR, only 5 candidates from the regional list will be chosen and the number of those elected in provincial constituencies will be 45. If the winning coalition receives less than 40% of votes special seats are added to the Council to ensure a large majority for the President's coalition.[1]
