Another executive has left James Packer’s beleaguered Crown Resorts group.

On Wednesday, the Australian casino operator announced that Robert Rankin has resigned as a director of Crown Resorts. Rankin previously served as chairman of Crown Resorts, but stepped down from his position in January.

Rankin was replaced by John Alexander, a longtime confidant of the Packer family, who was appointed as executive chairman of Crown Resorts with effect from February 1. James Packer also returned to the board more than a year after relinquishing his seat to focus on the casino group’s international expansion opportunities.

Alexander thanked Rankin “for his contribution as a director” as well as “his time as Crown Resorts chairman.” Rankin, for his part, said he’s “proud of the direction that Crown Resorts is taking and my role in its development.”
