The hostile takeover of Cadbury by Kraft has prompted the debate about takeover rules after the government found itself powerless to protect the confectioner from its US rival. The takeover of the transport company Arriva by Germany's Deutsche Bahn has now reignited the issue, although, unlike the Cadbury board, the directors of Arriva have backed the £1.5bn deal. The IoD is largely concerned about hostile takeovers, which can take place provided the company being taken over can secure a simple majority vote from shareholders.
