Stock indices traded little changed on speeches by the European Central Bank (ECB) officials. The ECB President Mario Draghi said in a speech in Frankfurt on Friday that the central bank is ready to use "all the instruments" to boost inflation in the Eurozone.

The ECB president pointed out that there are downside risks to the central bank's scenario.

"The downside risks to our baseline scenario for the euro area economy have increased in recent months due to the deterioration of the external environment. The outlook for global demand, especially in emerging markets, has notably worsened, while uncertainty in financial markets has increased," he noted.

The ECB Governing Council member Jens Weidmann said in a speech in Frankfurt on Friday that the low inflation in the Eurozone was driven by lower energy prices. He pointed out that the ultra-loose monetary policy could lead to risks.

"We need to be aware that the longer we stay in ultra-loose monetary policy mode, the less effective this policy will become and the more the attendant risks and side-effects will come into play," Weidmann said.

The Office for National Statistics released public sector net borrowing for the U.K. on Tuesday. The public sector net borrowing in the U.K. fell to £7.47 billion in October from £8.33 billion in September. September's figure was revised down from £8.63 billion.

Analysts had expected a decrease to £5.5 billion.

Public sector net borrowing excluding public sector banks increased to £8.2 billion in October from £7.1 billion in October 2014.
