Confidence among Eurozone businesses weakened further in April, strengthening the case for a rate cut this week by the European Central Bank.The European Commission said Monday, that a gauge of economic confidence in the 17-nation economy slipped 1.5 percentage points to 88.6, worse than the decline to 89.3 expected by economists and down from 90.1 a month earlier. A measure of sentiment among European manufacturers dropped to minus 13.8 from minus 12.3 in March. Despite the deterioration in data, Mario Draghi expects the region's economy to recover from a recession later this year, while economists forecast growth in the second quarter.
