OPEN LETTER: Sally Rooney is a writer, not a terrorist. Her books must be available to the public. Their withdrawal from sale, on the basis of ill-conceived and draconian anti terror legislation, is an affront to basic principles of free speech and expression so long taken for granted in this country. We categorically reject censorship - whether direct or indirect - and urge the government to change course, amending the legislation which has led us to this point of repressive absurdity.
