Commenting on concerns about RAAC concrete in schools in Wales, Laura Doel, national secretary of school leaders’ union NAHT Cymru, said: “A review of school buildings is being undertaken by the 22 local authorities, and so far there have only been two schools identified with this concrete.

“The Welsh government has pledged its support to schools and local authorities and schools are complying with the review to offer reassurance to parents as quickly as possible. NAHT and other education unions yesterday wrote to the Secretary of State for Education pressing her for answers to school leaders’ and parents’ questions and concerns.

“We are still in the dark as to why the UK government position has changed as schools were due to reopen and they need to provide full information immediately so that we are equipped to deal with any issues here in Wales.”
