Donald Trump has just tweeted WHAT

Today's lesson in why you should be cautious about the veracity of images on social media comes from Donald Trump, who granted a Twitter user's request to retweet a picture to honour his dead parents' memory.

However the image supplied by Twitter user "feckhead" was not all it seemed - it's actually a picture of notorious serial killer couple Fred and Rose West. Feckhead by name and by nature it seems.

The incident has spurned several other tongue in cheek tweeters to ask Trump to tweet pictures of their relatives.
