Ed Davey, Tom Hunt, Rupa Huq, Ben Lake, Ian Levy, Alan Mak, Lia Nici, Naz Shah.

I daresay "A Mak" or "R Huq" would work too.

Since not including a stamp should imply it's for an MP maybe it would be enough to choose a unique short name. I think there's more than one Ed, but Lia or Naz should be sufficient.

PM

Might work. Maybe I should go and parcel up some dogshit and try it.
