The world’s biggest PR firm claims to be an expert on trust – but is it?

Edelman, which will publish the latest edition of its trust barometer' at Davos, says trust is its legacy - but critics say its reluctant to follow its own advice

At the World Economic Forum in Davos, Switzerland this week, the public relations juggernaut Edelman will publish the latest edition of its trust barometer", an annual survey that purports to measure whether people around the world trust businesses, governments, NGOs and the media.

There's just one problem: even as Edelman promotes its brand and pursues clients with stern warnings about the importance of trust, critics charge the company appears reluctant to follow its own advice. The firm's clients have ranged from ExxonMobil to the Saudi government and members of the Sackler family, the former owners of the opioid manufacturer Purdue Pharma.
