Naina Lal, 28, is one of a handful of candidates from Pakistan's "transgender" community standing in national and provincial elections on Saturday. Known as "hijra", a catch-all term for transexuals, hermaphrodites and transvestites but usually indicating someone born male identifying as a woman, they have faced discrimination and ridicule for centuries. Living apart, they have traditionally earned a living as dancers, circus performers, sex workers and beggars.
