    Replace the pattern \s*\w+\s+\w+$ with an empty String:

    String s = "21 Lane Street London W10 2GH";
System.out.println(s.replaceFirst("\\s*\\w+\\s+\\w+$", ""));

    produces:

    21 Lane Street London

    A short explanation:

    \s*  # zero or more white space chars
\w+  # one or more alpha-nums (or underscore), specifically: [a-zA-Z0-9_]
\s+  # one or more white space chars
\w+  # one or more alpha-nums (or underscore)
$    # the end of the input
