"I am delighted Adele will be joining our growing agency in this senior role, bringing with her a wealth of experience leading a hugely successful team, superb brand and talent management expertise that goes beyond publishing, and an entrepreneurial vision to help steer the Riot ship."
Minchin, who starts her new role on 6 January, said: "I have spent 14 privileged years at the world’s most iconic publishing house, Penguin, and have loved every second of my time there working with the absolute best in the business. The opportunity to put all of my passions, values and expertise into a growing, nimble business with a mission to become the UK’s leading arts PR agency is however irresistible and very exciting. I have long admired the way in which Riot Communications has set about building a thoroughly reliable, creative, engaged and above all interesting and intelligent PR agency."
As well as Penguin, Riot Communications represents publishers including HarperCollins and book retailer Waterstones.
