I’m not who you responded to but presumably because it’s currently ranked the 29th most corrupt country in the world (out of 180). With a CPI score of 23 (where 100 is very clean and 0 is very corrupt).

The UK, in comparison, ranks as the 160th most corrupt country in the world with a CPI score of 71. So we’re not perfect either but we’re considerably better than Bangladesh.
