Julie Bentley, chief executive of Girlguiding, is placed at number five on a list of "game-changers" in the UK produced by the BBC Radio 4 Woman’s Hour programme.
Bentley joined the charity in 2012 from the Family Planning Association. Since then she has worked with the chief guide, Gill Slocombe, to give girls more say in the governance of the organisation.
Speaking about her inclusion on the list, she said: "I have been so inspired by the amazing girls and young women I have met in guiding. They prove that girls should be given more opportunities to step up, speak out, become leaders and be game-changers."
The other nine on the list are from the worlds of business, media and campaigning, including the journalist Caitlin Moran, the activist Carmel McConnell and Dido Harding, chief executive of the telecommunications company TalkTalk.
Top of the list is the anti-racism campaigner and newly appointed Labour peer Baroness Doreen Lawrence. The full list can be seen here.
