Market research group Sentix released its investor confidence index for the Eurozone on Monday. The index rose to 5.7 in April from 5.5 in March. A reading above 0.0 indicates optimism, below indicates pessimism.

"The process of economic stabilization of investors expectations has continued at the beginning of April," Sentix said in its statement.

"The Eurozone can benefit neither from a stabilization of the global economy nor from the measures of the ECB," Sentix added.

European Central Bank (ECB) Executive Board member Peter Praet said in a speech on Monday that the central bank would ease its monetary policy further to boost inflation in the Eurozone if needed. He pointed out that central banks should be active to reach price stability.

Markit's and the Chartered Institute of Purchasing & Supply's construction purchasing managers' index (PMI) for the U.K. remained unchanged at 54.2 in March, beating expectations for a decrease to 54.0.

A reading above 50 indicates expansion in the construction sector.

A slowdown in residential work offset rebound in civil engineering and commercial work. New business growth slowed down in March, while job creation weakened.
