Scientists funded by Cancer Research UK are among thousands of academics with pensions invested in the tobacco industry, it has emerged.
The pension fund for university staff owned £211 million in British American Tobacco as of March 2015, its fifth biggest equity holding.
Cancer Research UK ensures that its employees' pension funds are free of tobacco industry investments.
However, the charity funds many full-time academic posts at British universities whose pensions are invested through the Universities Superannuation scheme (USS), worth £49 billion in 2015.
Universities UK, which represents vice-chancellors and principals, said the USS was a responsible investor, but public health campaigners argue it is not possible to reform the tobacco industry and have called on investors to dump their holdings.
