Asos chief financial officer Helen Ashton is leaving the business in the summer, after informing the board of “her desire to move on from her current role”.
She will retire from the board on 30 April, and will remain at the business until 31 August to “ensure an orderly handover”.
CEO Nick Beighton, who was previously CFO, will cover her role until her replacement is found.
The etailer said: “The board expresses its appreciation for the contribution that Helen has made to the Group during her tenure and wishes her all the very best in the next stage of her career.”
Ashton joined Asos in September 2015. Before that, she was chief executive at debt management business Capquest and former finance director at Lloyds Banking Group.
