Stock indices traded lower ahead of the release of the European Central Bank's (ECB) interest rate decision. The ECB President Mario Draghi hinted at a press conference in January that the central bank may add further stimulus measures at its meeting in March as downside risks rose.

Market participants speculate that the ECB could cut its deposit by 0.10% to -0.40% and/ or expand its monthly asset purchases by €10 billion.

Britain's Prime Minister David Cameron will warn on Thursday that Britain's exit from the European Union (Brexit) would weigh on the pound.

"It means pressure on the pound sterling. It means jobs being lost. It means mortgage rates might rise. It means businesses closing. It means hardworking people losing their livelihoods," he will say according to extracts of his speech reported in local media.
