Eurozone inflation remained unchanged at a lower than expected 0.1% in November, according to official data, 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% inflation for the period, which is much lower than the ECB's official 2% target.

In March, the ECB launched a more than one-trillion-euro stimulus plan running through to September next year in order to snap a long period of low or negative inflation in the eurozone.

Inflation in November was dragged down by energy prices, led by oil, but this drop slowed to 7.3% annually instead of 8.5% the previous month, the data showed.

Mr Draghi on 20 November said the bank will "do what we must" to lift inflation as quickly as possible.

Central bankers of the 19-member eurozone are keen to fight falling prices because they can be poisonous for the economy, creating a vicious circle of falling demand and fewer jobs.

While falling prices might appear to be good for consumers, deflation can become entrenched if consumers delay purchases in the hope of lower prices later, which in turn prompts companies to hold off investment.
