I'm sure HMRC would love to meet up with Pompey again. I think it would go a little something like this
Pompey Bloke: 'Hey you guys, how you been? Now I know we screwed you over last time but I can assure you, this time....we have it all covered.....
HMRC: '**** off.' Pay up, or you're gone.
Pompey being smug the last time they defeated HMRC may, just may, come back to bite them in the arse.
