Ireland's bailed-out economy slumped back into recession in the second half of last year, and continued to shrink in the first quarter of 2013, official figures showed on Thursday.

GDP tumbled 1.0 percent in the third quarter of 2012 and by 0.2 percent in the fourth quarter, meeting the definition of a recession, according to revised data from the Central Statistics Office (CSO), which added that the economy shrank 0.6 percent in the first quarter of this year.
