The challenge to Dairy Crest's deal with Unigate from Robert Wiseman adds a twist to the changing shape of the entire UK dairy industry. Better known for liquid milk, if successful, Wiseman can either broaden its manufacturing base or sell off the bits it prefers not to develop. Unigate offers a perfect geographical fit for Wiseman. Chairman Alan Wiseman wants national coverage and acquiring businesses to sell them again immediately is not always cost effective. If negotiations are to re-open, the Dairy Crest share offer for the Unigate business will need to be beefed up. The former MMB manufacturing arm faces a strong cash challenge to its paper bid to prevail as Britain's largest dairy operation. {{PROVISIONS }}
