Why dont some people consider Andy Murray and Rory McILroy as British?

I think most people do accept that they are from the U.K., but as they are not English they receive less media coverage. Andy Murry and Rory McIlroy will be described as British citizens on their passports.>>"ADDITION">>>Hey, @"Old Know All", Rory McIlroy is from Holywood, Country Down,Northern Ireland,United Kingdom.
