Consultancy System1’s ‘Test Your Ad ‘platform gave the latest ad of Lock’s tenure, ‘The Gifting Hour’, a 4.6-star rating, the highest score the retailer has received since its ‘Excitable Edgar’ ad was released in 2019.

Lock said at the time: “Our shops are the beating heart of our brand and our customers love the ritual of Christmas shopping there – so we wanted to give the store a starring role in our ad for the first time.”

She shared on LinkedIn that she was leaving the firm for a new role which will be a “personal passion” but did not share any further details.

Lock said: “For now, I want to thank the talented JLP Customer team, fellow partners (past and present), and agencies for your friendship and support over the years,” she said.

“It’s been a privilege and I’m so proud of all we have achieved together. I wish you all every success and happiness.”
