Eurozone inflation remained unchanged at a lower than expected 0.1 percent in November, official data said on Wednesday, giving further encouragement to the European Central Bank to pump up its stimulus.

ECB president Mario Draghi is widely expected to boost the central bank's contested bond-buying programme on Thursday given low inflation levels across the 19 countries that share the euro.

The data from the EU's Eurostat statistics agency came in lower than analysts' forecast of 0.2 percent inflation for the period, which is much lower than the ECB's official two percent target.
