William Ewart Gladstone (1809–1898) was Prime Minister of Great Britain four times: 1868–74, 1880–85, 1886 and 1892–94. He called the Qur'an an "accursed book" and once held it up during a session of Parliament, declaring: "So long as there is this book there will be no peace in the world."

In this BBC audio report (thanks to Andrew), Gladstone's great grandson Christopher Parish and Professor Richard Aldous, head of history at University College Dublin, tie themselves into knots trying to come up with a reason why Gladstone would have approved of this reading room.
