Shares in Luminar, the collapsed nightclub operator, were delisted on Friday. The delisting came after the company was placed into administration at the end of last month. It is thought that administrators Ernst & Young have received a dozen expressions of interest for substantial parts of the nightclub operators’ estate. Bid interest has come from a range of firms, including Oakley Capital, the quoted investment fund that owns Time Out magazine, plus Sun European Partners and R Capital, the turnaround specialists. Hugh Osmond, the pubs and insurance entrepreneur, and Luminar founder Stephen Thomas are also said to be considering making offers for parts of the group.
