The board of Cadbury, the UK food group, is preparing to meet on Monday amid expectations that Kraft will go hostile with its takeover offer.

The US group is expected to stick close to the terms of its original £10.2bn ($16.9bn) proposal. Its offer will either formalise its original proposal of 300p in cash and 0.2589 new Kraft Foods shares per Cadbury share, or increase it slightly.
