WP_Query args to match given number of latest posts, both sticky and non-sticky

Hello,

I use the following code to query a give number (5) of most recent posts to be displayed in my sidebar:

<?php
	$leaflet_args = array(
	'showposts' => 5,	// display the most recent 5 posts
);
	$leaflet_posts = new WP_Query($leaflet_args);

	if($leaflet_posts->have_posts()) :
		while($leaflet_posts->have_posts()) :
			$leaflet_posts->the_post();

				get_template_part("content", "leaflet");

		endwhile;
	else: ?>
		<div>Oops, there are no posts.</div>
<?php
endif;
?>

Unfortunately, the ‘showposts’ number is just not working, since I have 4 posts marked as sticky, and they always show up in the query.
Is there an argument option I can pass to WP_Query not to prioritize sticky posts but just simply query the 5 most recent ones?

Thank you!
