The chief executive of food giant Kraft is believed to be planning her first visit to Cadbury's main UK factory in Birmingham since the US firm's controversial takeover of the chocolate-maker.
Irene Rosenfeld is rumoured to be planning a visit to the Bournville plant next month, although the company declined to confirm or deny the speculation.
Meanwhile, the TUC accused ministers of "dashing" hopes of a new approach to regulating mergers following the Government's response to a Business Select Committee report on the Cadbury sale.
The select committee accused Kraft of acting "irresponsibly" in pledging to keep open Cadbury's Somerdale factory in Bristol before confirming its closure after it had secured the sale.
The Government said it had no plans to amend legislation governing the power to intervene in mergers on public interest grounds, adding that existing powers gave appropriate scope to take action to protect legitimate national interests.
The Government added it would look closely at issues relating to the regulation of takeovers in the light of a review being conducted by the Takeover Panel.
TUC general secretary Brendan Barber said: "The Government has dashed hopes of a new approach to regulating mergers. This is disappointing, especially given statements and speeches made in the past by people who are now ministers.
"The Government should accept that the argument has moved on from a public interest test to a more sophisticated debate.
"They should consider the wider economics of mergers and acquisitions, including how best to stop conflicts of interest between advisers, top managers and shareholders, how to stop short-term speculators piling in against the long-term interests of both parties, and whether we need an economic test to ensure that takeovers do not destroy value in target companies."
