AMEY, the business services group mounting an pounds 80m hostile bid for Servisair, yesterday called on the airline services company's management to come clean about the identity of alternative bidders. Brian Staples, Amey chief executive (pictured), said: "We think this board needs to get on with things and stop wasting shareholders' money on their defence. Plenty of time has gone by since our offer [on 22 January]." Speculation about a rival to Amey's 200p-a-share cash bid has centred on Compass Partners. Servisair closed unchanged at 212p.
