Manchester-based Trunk has appointed Nick Entwistle as creative director after Adam Britton moved up into the managing director role.

Entwistle, the former creative director at MAGNAFI in Manchester, will work with Britton and the team on creative campaigns that deliver engaging experiences, working across film, animation, gaming, apps and social media.

The duo have known each other since they were two years old, attending the same schools before working together at Big Brand Ideas.

More recently they collaborated on the campaign that led to the NHS Choir beating Justin Bieber to Christmas No. 1.

Trunk models itself as the customer engagement agency for agencies and has produced work for the brands Paddy Power, Unibet & Kwik-Fit, in collaboration with the likes of Lucky Generals, No Brainer and Big Brand Ideas.

Entwistle has worked previously on campaigns for brands including Sofology, Betfred, Vimto, Very.co.uk, Irn Bru, Subway, Vauxhall and Bentley.

He also founded the popular Twitter account @OneMinuteBriefs which promotes brands and causes via social media by challenging their creative community on Twitter to respond to a brief using their creative instincts, and rewards the best ideas. He has just released his second One Minute Briefs book.

Entwistle said: “I’m excited to take on the challenge of working with Trunk. They are an agency that match my creative vision and I want to help make them famous for doing engaging, award-winning work.

“I’m looking forward to working with such a fast-growing talented team to make amazing things happen. Watch this space.”

Britton added: “I am delighted that Nick is joining the team. We’ve got huge ambitions for the agency so with his years of experience working on such a wide range of clients I’m sure he’ll help us achieve great things."
