Which newspaper identified J.K. Rowling as the author behind Robert Galbraith in 2013?

The Sunday Times identified J.K. Rowling as the author behind Robert Galbraith in 2013.

Rowling published The Cuckoo's Calling under the name Robert Galbraith in April 2013. The novel introduced private detective Cormoran Strike and was initially presented as the work of a first-time male author. Its true authorship was revealed in July 2013 after a linguistic analysis and subsequent reporting connected Galbraith with Rowling.

The Sunday Times reported the revelation, bringing widespread attention to the pseudonym. Rowling later continued the Cormoran Strike series under the Robert Galbraith name, while publicly acknowledging that she was the author.

This event is distinct from the publication of the first Strike novel itself. The Cuckoo's Calling had already been released before the newspaper disclosure. It is also separate from the later decision to adapt the books for television as Strike.
