The brief covers public affairs support, media monitoring and strategic advice in support of the ABPI's parliamentary affairs head Allison Bartlett.
She said H&K would be expected to work with think-tanks and form stakeholder partnerships and deal with issues such as access to medicines via the NHS. The ABPI has found common ground with patients' groups as it seeks to persuade the Government to make more drugs available through the health service.
H&K's managing director of corporate affairs, Andrew Pharaoh, will lead the three-strong account team, answering to Bartlett, who joined the ABPI last summer from Ketchum, where she was director of the ABPI account.
ABPI represents the main prescription pharmaceutical industry players in the UK, which spend almost £9m a day on research and development.
The ABPI's work on access to medicines in developing countries will still be done by Weber Shandwick's Brussels offshoot, WS Adamson.
