Emma House, deputy chief executive of the Publishers Association, is leaving the organisation after 10 years.
She was made deputy chief executive in 2017, after working as director of publisher relations for more than eight years.

"During her time at the Publishers Association, she has been responsible for a number of very successful projects and delivered a huge amount for members. Everyone at the Publishers Association wishes her well in the future."
The statement did not give the date of House's departure.
