Policy and training body the Directory of Social Change has appointed writer and journalist Nick Seddon as its new chair.
Seddon, who has been on the board for the past two years, takes over from Simon Hill, who has left because of work commitments after two years in the role.
Seddon, who at 31 is the DSC's youngest chair, will also take up the role of deputy director at think tank Reform in February. He is currently head of communications at Circle Health, and was a Third Sector columnist until last year.
In a statement, he said: "The new role is a challenging one, but it is an honour for me to have been elected to this post."
Debra Allcock Tyler, chief executive of the DSC, said: "Nick has proven his credentials during his two years on our board and has been an engaged and inspiring trustee.
"It is exciting to have a chair who is so passionately interested in the sector, particularly going into an election year, when the sector is going to be the focus of a great deal of attention."
