'To lose well over 500 nurseries, pre-schools and childminders every month is simply not sustainable.'
MPs have been warned there will be a "genuine childcare crisis" as figures indicate hundreds of nurseries and childminders are closing.
Early years leaders urged politicians to invest more money into the sector as Ofsted data indicated that 179 nurseries and preschools closed every month between January and March.
A total of 401 childminders fell off the early years register over the same period.
Between September and December last year, an average of 164 nurseries and pre-schools appear to have closed.
