Lesley-Anne Alexander is to retire from her role as chief executive of the RNIB, the sight-loss charity has announced.
Alexander, 56, who has led the RNIB for the past 12 years and who will stand down later this year, said it "felt like the time to retire" from the charity.
She was appointed CBE in 2012 and was recognised as Britain’s Most Admired Charity Chief Executive in the Third Sector Awards last year.
Alexander also spent six years as chair of the charity chief executives body Acevo.
In a statement, she said: "I have been at RNIB for over 12 years working in what I have often described as the best job in the world.
"The RNIB group of charities is stronger than it has ever been, we are reaching more people than ever before and our future, while always challenging, looks secure. Reflecting on how I want to spend the next phase of my life, it now feels like the time to retire."
Kevin Carey, chair of the RNIB Group, said: "Lesley-Anne’s passion and absolute commitment over the past decade has been instrumental in the advances RNIB and the wider sector have been able to achieve for people living with sight loss. Her energy and bravery in taking up opportunities and facing challenges have been an inspiration."
