Cash for dishonour

Goblin King "Tony, I have a file on you one inch thick, I have been waiting thirteen years, give me the keys to No. 10"

Tony Blair (the Vampire Slayer) "OK then, I can't be bothered any more ... one last condition, when you're PM, you'll get the CPS off my back"

Goblin King "OK"

... and so the Goblin King and Tony Blair (the Vampire Slayer) finally struck a bargain. And stuck to it.
