Nationality. 

There seems to be some disagreement in regards to Amir Khan's nationality at the moment, it keeps being switched from British to British Pakistani and so on. According to WP:OPENPARA, we do not put any emphases on ethnicity in the lead section unless it is an important part of why this person is notable in one way or the other (i.e. George Takei for example). I cannot see the importance of Khan's Pakistani heritage warranting a mention in the lead section as he is notable in his field as a British Boxer only. He was born in Britain, Fights for Britain, and has British citizenship. A user who has been responsible for a slow-moving edit war stated that Khan publicly identifies as British-Pakistani. However, if this is the case it will need a source, and if they can provide a reliable one I would be more than happy to see him described as British-Pakistani in the lead as personal identification is important. In all honesty, I've heard Khan talking about his Muslim faith a lot more than his Pakistani heritage...
