When was this meant to have happened (Is there any proof that it did?) was Andrew on the civil list at the time?
He had a taxpayer funded role as Trade Envoy. Whilst he was on these trips, he was staying longer to do golf all round the world, then sleazy sex with 40 women in Thailand and a lot we don't even know about because guess what? All of his travel records, how much money was involved, who he took on these taxpayer funded jaunts... all records have been sealed for 40 years. How convenient.
Oh, and apparently he took Epstein on a couple of these trips.
I think if it all came out, there would be a national outcry.
And he has been fully protected by QE2 whilst this has been going on for decades. It was brought to her attention many a time, right back to when he was in his twenties, it was all brushed under the carpet. He was untouchable. They all are.
