Linking to actual blog post from sidebar

I wanted the latest blog post to show in my front page sidebar i used the(the loop) and included

<?php
	$content = get_the_content('',FALSE,'');
	$content = apply_filters('the_content', $content);
	$content = str_replace(']]>', ']]>', $content);
	echo substr($content,0,160);
?>&hellip;

to shorten up the post. Now how can I include a read more link to the actual post? (not using the title permalink
