And dear Hassan
There is no double standard, it is customary as a guest to follow the host's roll's. This is an christian country and should be governed by one regardless. I don't remember if any christian or foreign background person has ever been a minister in Iranian government. or atleast no one I know about.
Wait so there has been no non-Muslim ministers in Muslim countries? Are you sure?
Let me start with my country, Iraq, which is far from being the liberal tolerant society that the UK is. It has had Jewish, Christian, and Sabaen Ministers and officials throughout history.
I'll give you some examples for now:
Eskell Sassoon: The founder of the Iraqi Parliament, Jewish.
Tariq Aziz: One of Saddam's closest advisers and held various ministries, Christian.
Minster of Health before the 03 war, Dr. Omeed Midhat, Christian.
The finance minister under Faisal II was Jewish. Forgot his name.
Most importantly, even
if there has been no no-Muslim ministers in Muslim countries, why should the UK emulate?
