Mother and father cut from passport
Parents will not have to identify themselves as either mother or father in applications for new British passports for their children, the Home Office has said.
The move, along with proposals which could see sex-free passports to allow transgender people to opt out of describing themselves as either male or female, follows concerns from gay rights groups.
The new forms, which are expected to be brought in by the end of the year, will contain additional options for "parent one" and "parent two", as well as the traditional "mother" and "father".
But Norman Wells, director of the Family Education Trust, said: "To speak of 'parent one' and 'parent two' denigrates the place of both fathers and mothers.
"Fathers and mothers are not interchangeable but have quite distinct roles to play in the care and nurture of their children."
An Identity and Passport Service (IPS) spokeswoman said: "It is essential that any parent provides the necessary information on their status as parents or guardians when applying for a passport on behalf of their child.
"This protects the interests of the child and ensures that IPS are able to issue passports securely and safely to the right person.
"The passport application form is therefore being updated to incorporate same-sex parents."
