Gold slipped on Friday, on course for a second straight week of losses, as a weaker euro sapped appetite for bullion amid the debt crisis in Europe while investors awaited a key US employment report later in the day for further trading cues. Spot gold slipped 0.3 percent to $1,558.25 an ounce by 0641 GMT, recovering from an intra-day low at $1,548.50. Gold fell 6.3 percent in May, the steepest monthly fall since December. It was headed for an almost 1-percent weekly loss.
