A council planning the closure of four primary schools because of plunging pupil numbers is facing legal action from parents because academies and faith schools are excluded.
Colvestone Primary School is one of four maintained schools that will close at the end of this academic year if Hackney council goes ahead with its plans.
However, campaigners have issued a pre-action letter that threatens judicial review if proposals are not scrapped.
They say the focus on closing local authority-maintained schools will leave them without the option of a non-academy, non-faith school.
