The July 13 issue of the 125-year-old title includes content that reflects The Duchess of Cornwall’s love of horses and dogs. It also includes her most cherished view, her favourite recipe and her champions of the countryside.

It will also celebrate the work of some of HRH’s 90-plus patronages, from Barnardo’s to The Royal School of Needlework and The Royal Society of Literature.

The commemorative issue is supported by an ITV programme, Camilla’s Country Life, which follows HRH’s journey as she works on the special issue.

Future’s subscription marketing team has capitalised on this increased awareness with a coordinated campaign to celebrate 125 years of Country Life, with a particular focus on the souvenir guest-edited issue by HRH The Duchess of Cornwall and the 6 issues for £6 subscriptions offer.

Future said the campaign has involved testing new marketing channels, assessing the potential audience size and market opportunity of Country Life magazine, and showcasing the additional value of brand factors such as the TV show.

Country Life Editor-in-Chief Mark Hedges said: ‘It is a great honour that The Duchess of Cornwall has agreed to guest-edit Country Life in July. Her Royal Highness is a passionate countrywoman and we’re delighted that she follows her husband in presiding over this commemorative edition.”

Country Life was guest-edited on 14 November 2018 by HRH The Prince of Wales in honour of his 70th birthday.
