Guinness owner Diageo top as GlaxoSmithKline falls to bottom of Good Governance survey

A recent bribery scandal and excessive pay policies have sent pharma giant GlaxoSmithKline to the bottom of the UK's Institute of Directors' (IoD) corporate governance survey.

The third annual Good Governance Index (GGI) ranked GSK as the worst company among London's largest listed firms when measured against 47 indicators in five broad categories including board effectiveness, audit and risk/external accountability, remuneration, as well as shareholder and stakeholder relations.
