The Prime Minister's Dog Resigns

Dillon, the prime minister's dog has resigned with immediate effect. He walked into borris johnson's office and curled out a large turn right on the carpet. Do we know what pushed him over the edge? I think there was just a feeling around his camp that he couldn't in any good conscience stay with the prime minister and still be a good boy. And i'm confident that when lord donkeyshagger comes back with his apo, we'll have a much clearer picture.
