Police Scotland posted on one of their verified social media channels that they are “tired” of the SNP “going on about” a second independence referendum.

The profile picture on the official Twitter account for the force in Edinburgh was also changed to include a “Yawn” sign.

The post, tweeted by verified account @EdinburghPolice, read: “I just added @scotlandinunion’s #Yawn badge as I am tired of the @theSNP still going on about #Indyref2.”
