More than 100 schools were fully or partially shut days before the beginning of the new term over fears a type of concrete used to build them could suddenly collapse.

The Department for Education (DfE) is facing questions about why it waited until the eve of the new school year to make the announcement, with teachers left scrambling to find alternatives for pupils.

Meanwhile, parents are demanding answers over the short notice as Schools Minister Nick Gibb said on Friday that more educational settings - as well as other public buildings like hospitals and court rooms - could be set to shut.

Schools Minister Nick Gibb said on Friday that a full list of schools affected by RAAC,  reinforced autoclaved aerated concrete, will be published in the afternoon. 

The DfE is understood to have contacted more than 100 schools on Thursday to advise them to fully or partially close.

So-far, the local authority in Bradford revealed on Thursday that Raac was detected in Crossflatts Primary School and Eldwick Primary School in the West Yorkshire city.

Both interim and long-term alteration works are being carried out to ensure children can be accommodated on the two sites, according to Bradford Council.
