Although it could have been a bit more blatant.....
"Hello, is the the old codger that lives at this address...
Good, this is Tory Central Office calling. Teresa May, y'know, the Prime Minister. Yes that's the one. She has a special message for you. Would you like to hear it? You would. Great. Here it is.
"Put your slippers on an get your f**king a**e down to the polling station. Turn right outside your house and it's 200 yards down the road with a big sign outside saying "Polling Station." When you get there vote Conservative, because if you don't I will lose the election and you will be forced to house a homeless family of Syrian Gypsies."
Yes Syrian Gypsies*, they're the worst. That's right. Better get moving. Bye bye.
*I have no idea if there are any travelers in Syrian, but I doubt CCO knows either.
