Editors’ Note, March 6, 2020: Portions of this article refer to elements of a report in The Guardian newspaper that has since been removed from its website and replaced with an editorial statement after Yana Peel challenged the paper’s report.

LONDON — The chief executive of the Serpentine Galleries, Yana Peel, resigned on Tuesday after a newspaper investigation revealed she had connections to a cybersecurity firm whose technology has been used to target journalists and human rights activists.

“In light of a concerted lobbying campaign against my husband’s recent investment, I have taken the decision to step down as C.E.O.,” Ms. Peel said in an emailed statement. “I am saddened to find myself in this position,” she added.

The Serpentine Galleries is one of London’s most popular art museums, and has recently presented exhibitions by Marina Abramovic and Christo. It has also championed artists who have faced persecution such as Ai Weiwei.
