Macquarie Bank, the Australian investment bank, is the latest mooted potential bidder for Spirit Group. The bank approached Spirit last week about making a formal offer, according to a report in the Financial Times. Macquarie’s assets include airports, utilities and property. Earlier this month the bank announced plans to raise up to Australian$996m (£425m) to fund media acquisitions around the world. Macquarie could face competition from an ever-growing number of interested parties. Punch Taverns has been rumoured to be considering a £2.5bn joint bid for Spirit with Mitchells & Butlers. Last week Robin Saunders, the former WestLB banker who last year set up Clearbrook Capital Partners, was reported to be considering a £3bn bid for the company. Robert Tchenguiz is also thought to be working on a bid for Spirit. An IPO has not been ruled out by Spirit’s owners Texas Pacific, Blackstone and CVC Capital and Merrill Lynch.
