Because London is English speaking.

Where else can they hide out?

Can't do it in Singapore.

Can't do it in Indonesia.

America is too dangerous with all the random bullets flying around.

Other countries do not speak Malay or English as a vernacular language.

So UK lor. And London is the most cosmopolitan place in the UK lor. You think rich politicians want to hide out in Leeds or Birmingham meh? Or worse still, Liverpool? LOL!!!

I stand corrected, good sir!

Wonder how Canada looks as a hideout destination as well, hmm......
