Tim Nuthall will join the agency's Brussels office after three years at the Labour Party press office.
He follows his ex-boss - former Labour Party head of press and broadcasting Jo Murray - in to the agency world. Murray recently moved to Fishburn Hedges as an associate director (PRWeek, 18 January).
Nutthall is the latest in a number of new recruits to add to Fleishman-Hillard's lobbying credentials.
PRWeek recently revealed that Harri is to join the agency's public affairs arm as a senior consultant.
In 2007, the agency hired Simon Benson, a former special advisor to current Home Secretary Jacqui Smith, and two Conservatives:
Sophie Pim, who had worked in David Cameron's private office as operations manager, and Shaya Raymond, previously a political researcher to shadow cabinet member Theresa May.
