FINAL UPDATE:
Guys, my immigration journey has come to an end today! I received my shinny new passport today 07/05 dated 06/05 and I am glad its all over which at times felt like an eternal journey

The whole passport process took 21 working days. My passport was printed on the same day as my interview.
Just FYI that I did not receive my passport through DX Secure. I was at work today so when I came back there was lot of mail in my letter box and between all those letters was sandwiched a small white passport size letter saying in bold "Her Majesty's Passport office" "This is not a Circular..Important documents enclosed"....I have a feeling that as I live very near to one of the passport office and I had my interview there as well..maybe they did not give my passport to DX Secure and delivered it through their own delivery system .. one benefit of living close to HMPO lol
Lastly, I would thank everyone on this forum who have been very helpful not just for my citizenship application but since I started my journey from HSMP...hats off to all of you..I will be checking this forum whenever I get time to help others..cheers all.
