Baroness Sue Campbell will step down as the chair of the Youth Sport Trust after more than two decades, prompting the organisation to search for a new figurehead.

Campbell will officially leave in December, ending 22 years of service with the organisation, which she headed up firstly as chief executive and latterly as chair.

She said it had been a “difficult decision” but it was the “right time” to move on.

“It has been an honour to steer the Trust on its course for many years and see the amazing impact we’ve had on millions of young people,” she said.

“I’m delighted to accept the honorary title of Life Ambassador and look forward to seeing the Trust continue to grow and flourish in the future.”

Sir John Beckwith, founder and president of the organisation, said Campbell had given “outstanding service”.

“I am immensely grateful for her inspiration, leadership and the extent to which she has invested herself in the life and work of this important charity,” he added.

“I hope the search for a new chair will attract someone with the same passion and belief in making a difference to young lives through sport to take the charity forward into a new era.”
