Re: As paid for by the Pakistani tax payer..
I think you will find that T Blair travels with entourages just as big if not bigger than Shaukat Aziz. I seem to recall a trip to Saudi Arabia where there were about 40 "business men" accompanying Blair not to mention the diplomats and politicians that also went with him.
With regards to corruption, I don't think our politicians are more corrupt than Western politicians just that they aren't as good or as subtle. I mean what exactly was Mark Thatcher's contribution to the Al Yamamah deal that was worth in excess of £10m?
