Former sports minister Richard Caborn has been tasked with promoting Sheffield to employers and investors.
Sheffield Council leader Julie Dore has made him an unpaid ambassador for business and industry.
The former MP, who has been involved with the development of the Don Valley site as an Olympic Legacy Park, said: “I take great pride in representing Sheffield and will use my knowledge and experience to support the city in retaining its place as one of the top UK cities.
“We’ve taken significant strides in turning exciting technological ideas into apprenticeships, jobs and prosperity,
“This project will give to a wider audience the story of the city’s resurgence and its potential for the future.”
The new role of envoy will give the city a tremendous advantage, Coun Dore said.
“He will support us in promoting Sheffield externally, contribute to bringing forward the right ideas and policies, and will use his influence in key areas.
“Richard has always been a great asset for the city and has fought hard for Sheffield, so it made sense to ask him to continue to use his experience and track record in this critical period of the city’s development.”
Mr Caborn, whose background is in engineering, serving his apprenticeship at Firth Browns.
He was part of the team that has seen the Advanced Manufacturing Research Centre grow.
