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. On November 17, the Senate approved the constitutional reform in its final instance; Northern League leader Umberto Bossi attended the discussion and the voting, returning to the Parliament, even if just as spectator, after his illness. During the vote, Domenico Fisichella announced his opposition to the reform, and his immediate resignation from the party, going against the party line about the issue. Italian MPs quite easily change party and even coalition: in the legislature between 1996 and 2001 15% of MPs did so.
