One in six people in the UK say they no longer trust companies, according to new research conducted by Lansons Communications and Opinium.

The study reveals the 50 companies most trusted by the British public, with Marks & Spencer in top spot with almost twice as many mentions as second placed John Lewis.

Yet it also shows "corporate Britain has a problem with trust", according to Lansons chief executive Tony Langham. Some 17% of the population say they don’t trust any companies anymore, while 31% say ‘trust is not really a feeling they have about companies’. The league table is based on just over half (52%) of people, who state they still trust ‘a few’ companies, asking them to list the companies they still trusted.
