Italy's FTSE MIB outperformed, up 1.4 percent.

Italy's biggest banks Unicredit and Intesa Sanpaolo were among the top gainers, up 2.6 percent each, while Mediobanca, UBI Banca, and Banco BPM also rose as much as 5 percent.

Outside of politics, Oslo-listed aluminium firm Norsk Hydro was the biggest faller, down 7.3 percent after announcing it would shut all output from its Alunorte alumina refinery in Brazil.

Tesco shares fell 5.5 percent after the UK's biggest retailer reported first-half profits which missed analysts' forecasts.

"Good like-for-like, but weak bottom line points to margin destruction," said a trader.

Shares in French tech consultancy Altran jumped 11 percent to the top of the STOXX, with traders citing an upgrade from broker Kepler Cheuvreux.
