    Are you asking about the apostrophe or the capitalization? – Mark Beadles Mar 9 '12 at 16:34

    When downvoting or voting to close it is good practice to add a comment specifying why, at least for politeness. – nico Mar 9 '12 at 16:55

  • I down voted and voted to close because the question title is about possessive apostrophe, and the question was not, although now it seems to be. – Matt E. Эллен Mar 9 '12 at 17:04
  • I'm still not quite sure what the question here is, so I'm closing this pending clarification from the OP. – RegDwigнt Mar 9 '12 at 17:30

When an initialism is made possessive, it is treated as any other word. Also, never change the capitalization of an initialism. UK's is correct:

some of the UK's longest tunnels
