In June 1990, The Times ceased its policy of using courtesy titles ("Mr", "Mrs", or "Miss" prefixes) for living persons before full names on first reference, but it continues to use them before surnames on subsequent references. The more formal style is now confined to the "Court and Social" page, though "Ms" is now acceptable in that section, as well as before surnames in news sections.
When The Times ceased its policy of using courtesy titles, it continued to use them for what kind of name on references after the first? (If the question is unanswerable, say "unanswerable")
surnames
