Grant automatic UK citizenship to those born to a British mother before 1983

Unfortunately, while people born to a British mother before 1983 can apply for British citizenship, this is not automatic, and only applies once granted. This can mean that people born to those who were not automatically British citizens – because they were born to a British mother before 1983 – also miss out on rights to British citizenship, as even once someone has applied for British citizenship (using form UKM), this is not backdated and so does not grant citizenship to children they have had before that time.
