A former director at the tobacco giant Philip Morris International (PMI) was handed a role on an influential expert committee advising the UK government on cancer risks, the Observer can reveal.

Ruth Dempsey, the ex-director of scientific and regulatory affairs, spent 28 years at PMI before being appointed to the UK Committee on Carcinogenicity of Chemicals in Food, Consumer Products and the Environment (CoC).

The committee’s role is to provide ministers with independent advice. Yet since taking up the position in February 2020, Dempsey has continued to be paid by PMI for work including authoring a sponsored paper about regulatory strategies for heated tobacco products.

She also owns shares in the tobacco giant – whose products include Marlboro cigarettes and IQOS heated tobacco sticks – and receives a PMI pension. On social media she continues to engage with senior staff at the company, including liking LinkedIn posts for the chief communications officer and the vice-president of public affairs.

There is no suggestion that Dempsey has acted improperly or failed to declare her interests, which are listed in committee documents. She said she had always complied with the rules and that her contributions to the CoC were based on her scientific training and “decades of experience in the field”. She also said she was “no longer a representative of the tobacco industry” given she had retired and had disclosed details of her career and financial interests during the application process.

Prior to Dempsey’s appointment, the CoC was involved in reviews of both e-cigarettes and heated tobacco products, two of PMI’s product lines.

Dempsey is believed to have been appointed to the committee following an evaluation and interview conducted by a three-person panel, including a Department of Health and Social Care (DHSC) official, after stepping down from her full-time role with PMI to establish her own toxicology consultancy in the summer of 2019.

Dempsey said she was “very sorry if anyone feels that my presence on the committee is inappropriate”.

When she joined she did not have any active consultancy agreements with PMI but said the two she has had since had been properly declared. She also declared potential conflicts of interest when topics arose “that could be related to work I was doing as a consultant to any company”.

“In the five years that I have been a member there has been no topic related to tobacco products. If there had been, I certainly would declare my conflict of interest and would always follow the guidance of the committee chair regarding participation,” she said. She added that she had “never passed confidential or privileged information to PMI, and would certainly never do so”.
