I think John Mortimer, who most of us know as the author of Rumpole, fought for the publication of Lolita as well as Lady Chatterley’s Lover.
He worked on free speech cases, but I don't know if he was involved with Lolita.
If he was that could explain this in the article:
While promoting her film The Bookshop last year, actor Emily Mortimer also talked about the “sanctimony” of #MeToo, telling the Telegraph: “Lolita would have a hard time being published today.”
But The Bookshop is also about a bookseller who decides to sell Lolita.
