LIMA (Reuters) - The center-right government of Peru’s embattled President Pedro Pablo Kuczynski canceled its scheduled auction of a $2 billion copper project, Michiquillay, on Wednesday amid a growing political crisis, two government sources said.

The regional bloc Organization of American States said earlier on Wednesday that it was preparing to send a delegation to Peru, the world’s second biggest copper producer, to observe the “political situation” at the request of Kuczynski ahead of a vote in Congress to oust him on Thursday.
