[jQuery] Select Last

[Panman]

Sounds simple but I cannot get it to work. Here is the structure.

<ul class="list">
  <li><a href="#">Abc</a></li>
  <li><a href="#">Abc</a>
    <ul>
      <li><a href="#">Abc</a></li>
      <li><a href="#">Abc</a></li>
      <li><a href="#">123</a></li>
    </ul>
  </li>
  <li><a href="#">Abc</a></li>
  <li><a href="#">Abc</a></li>
</ul>

I want to get the last <a> in the _sub_ list. Here is what I've tried
with no success. Ideas?

$('.list li li:last a').addClass('last-li');
$('.list li ul li:last a').addClass('last-li');
$('.list li:has(ul) li:last a').addClass('last-li');
