Parents are taking legal action in an attempt to prevent the closure of three nursery schools in west London.
A judicial review claim has been lodged against Hillingdon Council.
Out of the blue in August the council informed parents and carers that the Uxbridge, South Ruislip and Nestles, which is in Hayes, early years centres would close in December.
The centres provide more than 100 places for children under five.
The council says they make an annual loss of £500,000 and that can no longer be sustained.
