Problem with header.php – latest post will not align left

Hi I have a problem where he latest post title is aligned to the right on my blog – http://www.lettersunite.com/blog.

I thought it was to do with an H2 formatting issue but now believe it is to do with the menu div in the header.php.

Any ideas? I can post the code if necessary.

Thanks
