Oil prices retreat

Oil prices fell on Thursday as traders booked profits following recent gains and weighed up the impact of a weakening dollar on crude futures against disappointing Chinese economic data. Prices had risen in recent days thanks to a weaker dollar and signs that a global supply glut was easing. In late London trading, Brent North Sea crude for delivery in June eased seven cents to stand at $66.74 a barrel. US benchmark West Texas Intermediate for June delivery fell 90 cents to $59.60 a barrel compa
