Dubai a popular place for medical attention for the unpopulars ( with the West that is ) Bin Laden also rumoured to have been there (for treatment that is ) some years ago now .
I expect the KL trip is just to move more goodies for the retirement / hiding place for Grace and Bob ( if he has much time left ? ).
He has a soulmate in Mahatir - possibly the two most anti - Western leaders of Commonwealth countries in history. At least MM loves his country and people and has done his best to improve their lot - what has Bob done for his people ?
