GM Real Estate, headed up by two of the biggest ‘closers’ in the Property World, Tony Gibbon and Tony McCurley, are close to being taken over by Colliers International in a deal that will see the property giant enhancing its presence in the City market. The deal is believed to be at a premium price of £25m – suggesting that Colliers are keen to wrap up a deal for the company who last year rejected the advancements of CBRE.
