The bottom line in doing business with the Saudis is that you do it their way or not at all.
If you can persuade them that their old way is now illegal in this country, as has clearly been done already, and they still want to do business with us, we should not then rake over practises that were not, in any case, illegal at the time.
If the Typhoon deal is signed despite the best attempts of the BBC and Guardian et al to sabotage it (probably to the unbridled joy of the Americans and French) it will testify to the desirability of the product - not the way we conduct our affairs.
Let's get real!
