One anonymous author who never made it into the Guardian's great poets series has apparently been lurking in obscurity around Whitehall. Who penned this ode to the prime minister may never be known:

"At Downing Street/ Upon the stair/ I met man who wasn't Blair/ He wasn't Blair again today/ Oh how I wish he'd go away."

It is, of course, derivative. But adapted, original or otherwise, can you do a better short verse tribute to any of our political leaders?
