I must warn you, having suffered from the human desire to grab cash, encouraged and assisted by police, PR people, media and you as DPP, that you are absolutely guaranteed to come to an appalling end within months, whether or not you become Prime Minister.
Your instruction to police to tell people wanting to make a few thousand quid, tax free, that "You will be believed even if you are lying and even if your victim is Prime Minister because we have to investigate, prosecute and convict without fear or favour" - makes it absolutely certain that you are in the sights of several false accusers or maybe even true accusers.
The first accuser will pocket a million quid. The rest of the band waggoners will make hundreds of thousands.
Good luck.
