Oil slid in early Asian trade on Monday, with U.S. crude falling close to a six-year low, after Greece’s election results heightened uncertainty in the euro zone and depressed the bloc’s currency against the dollar. Greece’s left-wing Syriza appeared on course to trounce the ruling conservatives in Sunday’s snap election, setting up a possible confrontation with international creditors. March Brent crude fell 44 cents to $48.35 a barrel by 0442 GMT, wiping out light gains made on Friday after the death of the Saudi King Abdullah, but off an early low of $47.85.
