Ed Cox is to stand down as director of IPPR North after nine years.
He will leave the thinktank in May to join the Royal Society of Arts as its director of public services and communities.
Mr Cox said he was proud of IPPR North’s achievements, saying of its Northern Prosperity is National Prosperity 2012 strategy: “Few could have imagined that such an engaging policy debate would follow in the name of the ‘Northern Powerhouse’ and industrial strategy.”
He added: “Through our contributions to the debate on schools and skills, our blueprint for Transport for the North which is now unfolding before us, our recent Northern Energy Strategy, our annual State of the North reports, and in so many other ways, we have consistently set the Northern Powerhouse agenda and brought meaning to it.
“My passion for a more autonomous north is undiminished.”
IPPR director Tom Kibasi said: “Ed Cox has been a superb director of IPPR North, making an enormous contribution both to the development of public policy in the north of England and to the wider institute. He has brought passion, energy and vision to the role. We will miss him and we wish him every success in the future.”
The institute will begin recruiting for a successor to Mr Cox today.
