There is something dodgy about Hasnat Khan. This is a guy who is a Pakistani muslim. He married a 29 year old muslim woman after Diana and divorced her after 18 months. He was famous. Then he went to work in Malaysia. After that he is now working again in the UK. He will be earning slim pickings there. Unless you're on Harley St you are maxing out at 200-300k (GBP). He has a house in Pakistan and the girl he married was Afghan royalty, who he divorced. This is not the lifestyle of someone earning a UK consultant surgeon salary. He is also related to Imran Khan (cousin-ish).
There is another angle to this. Why did Diana pick on TWO muslim men to have relationships with? Muslim men in the UK who are eligible but not married are a rarity - many of them may be gay. I have never met a successful muslim professional in the UK over 30 who is not already married. Diana found two in quick succession. What's the probability?
So, was she primed to meet those people and have relationships with them?
Anyway, bottom line is that Hasnat Khan seems dodgy. He should be easy to get hold of if anyone wants to ask him wtf was going on!
