In this, the fifth issue of Great British Brands, the watch word is optimism. At the start of the new decade, adopt a 2020 vision to look ahead and see that your glass is half full, as Nicholas Foulkes finds in his survey of the luxury landscape. Roya Nikkhah asks the question ‘Is The House of Windsor our greatest British brand?’, which is fitting as fashion royalty, Vivienne Westwood designed a bespoke cover dress, modelled by her granddaughter, Cora Corré. In addition to stories from the best brands Britain has to offer, Bill Prince recognises the saviours of luxury brands and Lisa Grainger profiles six green heroes that put purpose over profit.
