The chief operating officer of aAim, the leisure property group backed by a number of high-profile individuals, has left to join GI Partners. Colin Rowlinson, who was finance director of Yates Group under GI Partners’ brief ownership in 2004, has teamed back up with the private equity group to help with its leisure investments, such as pub company Orchid Group. GI is also invested in holiday park firm Park Resorts. Both businesses are understood to be highly leveraged and could benefit from Rowlinson’s leveraged-buyout background. Led by Rufus Hall, Orchid was formed from the acquisitions of 290 pubs from Spirit Group and a clutch of restaurants from Noble House. The departure of Rowlinson from aAim comes amid reported uncertainty over the business, which is partly backed by Halifax Bank of Scotland (HBoS). There have been fears that the bank, which announced a £12bn takeover by Lloyds TSB two weeks ago, is reviewing all of its property joing ventures and debt facilities. The property group is 20% owned by HBoS. Rowlinson, a former Nomura executive, joined aAim last year after previously working with chairman Mark Tagliaferri.
