The Prime Minister has set Twitter abuzz after a user posted what appears to be a Photoshopped effort to replace Scott Morrison's shoes on his official website.

The discovery, which is being described as "shoegate", appears to show a pair of white shoes poorly edited over the PM's original pair on the site pm.gov.au.

The original photo of Mr Morrison with his own shoes appears in his 2018 Christmas video, which was tweeted out on Christmas Eve.
