Whitehead, who joins next month, will oversee all corporate and financial comms as well as public affairs efforts, reporting directly to CEO Philip Bowman.
Whitehead said he would carry out a review of the corporate affairs function, adding that hiring extra staff was an option: 'I will be looking at all aspects of the area I'm covering. The company is committed to communications and I want to see how that function can be improved.'
Reporting to Whitehead will be the nine-strong in-house corporate affairs team and retained corporate and financial agency Cardew Chancery.
While Allied Domecq has staff covering government affairs, policy and internal comms, there is currently no senior in-house corporate communications role. The role of chief spokesman on corporate issues will be handled by Whitehead.
Also reporting to Whitehead is the Washington DC-based senior director of international government affairs Bennett Caplan.
Consumer PR teams for the company's brands, which include Malibu, Courvoisier and Tia Maria, are not covered by Whitehead's remit. They report to the marketing team.
He replaces Jane Mussared who left last month to return to her native Australia.
Whitehead joined Eli Lilly five years ago and as European corporate affairs director oversaw all comms, product PR and policy work, covering 65 staff.
The drugs giant is now looking to replace Whitehead.
Whitehead has also had stints with Diageo as external affairs director and Glaxo Wellcome, now GlaxoSmithKline, where he was head of communications.
Allied Domecq is the world's second largest drinks distiller, after Diageo.
