Kraft has proposed buying Cadbury in a £10.2bn move announced today.
Retained agency Brunswick has been handling the announcement and dealing with press enquiries.
It has been reported that Cadbury has ‘unequivocally' rejected the approach.
Finsbury handles Cadbury's financial PR, having won the account from Maitland late last year. Cadbury recently hired Trevor Datson as its global head of financial comms, replacing Alex Harrison who left the firm in June to become director of corporate media relations at GlaxoSmithKline.
Cadbury owns the Dairy Milk, Green & Black's chocolate brand and Trident gum brand. Kraft's brands include Kenco coffee, Oreo biscuits and Toblerone.
