The only real way forward for HMRC
Staff HMRC completely with chimps, I believe that this will increase efficiency (from its current levels anyway) and improve public approval (especially if you make them wear suits, who doesn’t like the PG Tips adverts! Think of a whole government department staffed with them! Brilliant!) Plus you can pay them peanuts.
Penguin.. because penguins would also be an improvement, and bring their own suits.
