The Bank of Spain in Madrid

Spain's economy will sink deeper into recession this year, the Bank of Spain said on Tuesday, sending a stark message to the government as it prepares to revise its own growth forecast.

In its annual update of economic forecasts, the central bank said it saw Spain's economy shrinking by 1.5 percent in 2013 following a 1.4 percent contraction last year as austerity continues to exacerbate the effects of a burst property bubble.
