The MS Society, the charity for people with multiple sclerosis, has appointed Michelle Mitchell as its chief executive.
Mitchell is currently charity director general at Age UK and will join the society in September.
Simon Gillespie, the charity’s previous chief executive, left in February to become chief executive of the British Heart Foundation. Patricia Gordon, director for Northern Ireland of the MS Society, has been the acting chief executive since then.
During her time at Age UK, Mitchell has overseen several high-profile campaigns and played a key role in the merger of Age Concern and Help The Aged to create Age UK.
She previously worked for the NSPCC as its government affairs adviser. Before that she worked as head of the parliamentary unit at Charter 88, the now-defunct campaigning group for constitutional and electoral reform.
Mitchell is a trustee of Platform51, the female equality charity, and of the British Gas Energy Trust, a charity that supports people who struggle to pay their fuel bills.
Mitchell said: "I am delighted to be joining an excellent team at the MS Society and I believe the charity’s inspirational work, from world-class research to practical information and support, is fundamental to improving the lives of people with multiple sclerosis. I am looking forward to working with staff and volunteers to build on the excellent achievements of the past 60 years."
Hilary Sears, chair of the MS Society, said: "Michelle has a successful track record as a leader and brings with her extensive experience in public affairs, strategy development and research. The trustees and I are looking forward to working with her."
