The European Central Bank (ECB) released its minutes of March meeting. According to the minutes, the Governing Council reiterated to keep its monetary policy "for as long as needed".

Markit's and the Chartered Institute of Purchasing & Supply's construction purchasing managers' index (PMI) for the U.K. fell to 57.8 in March from 60.1 in February, missing expectations for a rise to 60.4.

The decline was driven by slower rise of output and new orders.
