Fourth Berlusconi government — populist-centre-right PdL-Lega majority hitting the GFC within months, running on low-tax supply-side rhetoric but forced into Tremonti crisis orthodoxy. Signature measures: 'Tremonti-ter' accelerated depreciation for machinery investment (Jul 2009), ICI primary-residence property-tax abolition (2008), Robin-Hood energy-firm tax surtax (2008), anti-crisis decree-law D.L. 185/2008, Alitalia restructuring under CAI (Jan 2009), and — under mounting bond-market pressure — successive 'manovre' austerity packages (D.L. 78/2010 ~€25bn, D.L. 98/2011 €48bn, D.L. 138/2011 €54bn) after the Aug 2011 ECB Draghi-Trichet letter demanding reform. Also: Lodo Alfano immunity law (struck down 2009), prolonged Mediaset-conflict-of-interest and 'Bunga Bunga' scandals, Ruby trial opened Feb 2011. Left-right: right of centre, populist-clientelist mode. Popularity: PdL+Lega 46.8% / 340 seats in 2008 general (decisive majority), Berlusconi personal approval collapsed from ~62% (mid-2008) to ~22% (Nov 2011); lost majority Nov 8 2011, resigned Nov 12 after BTP-Bund spread spiked over 550bps. Coherence: low — fiscal populism (ICI cut) vs crisis austerity (manovre) zigzag, legal-political scandals consumed reform bandwidth.
