Avis Gilmore, deputy general secretary, National Education Union: 

"The NEU has raised concerns with Government in relation to the wearing of face coverings in schools, and its lack of consistency with guidance on other public places.  While the DfE and PHE have reaffirmed their position that coverings are not necessary, this is an issue that must be subject to regular review in light of developments in scientific opinion, experience and practice elsewhere. Therefore we will continue to question this in advance of the anticipated full return in September.  

"It remains our view that no member of staff or pupil should be prevented from wearing a face mask if they wish to do so and we anticipate that the majority of schools and colleges will respect this."
