The fourth Garden Retail Power 100 sees more than 20 changes less than a year since we published the previous list.
Industry leaders such as David Gwyther, Gillie Westwood and Richard Plowman have retired, while Nicholas Marshall, Bernard Burns, Mark Pearson, Neil Fishlock, Lorrie Robertson, Jeff Kwiatowski, Phil Slinger, Andrew Maxted, Nick Davison, Ewan Sutherland and Caroline Spelman have left the garden retail industry or taken on new roles.
We have chosen people to represent sectors and largely kept to one representative per company elsewhere. The Power 100 is a Garden Retail view, gleaned from conversations with industry watchers, and is meant as a source of debate. Email email@example.com with any views.
