Teachers in Wales and the south of England will strike on Thursday in a long-running dispute over pay.
It is the third day of walkouts by National Education Union (NEU) members after teacher strikes took place in northern England on Tuesday and the Midlands and eastern regions of England on Wednesday.
The NEU has estimated that around 200,000 members will strike across the three days of action this week, with the “majority of schools” expected to either restrict access to pupils or fully close.
A poll by Ipsos suggests that three in five (60 per cent) parents and guardians back teachers taking strike action, but many (43 per cent) are worried about their children catching up on work missed because of the walkouts.
Picket lines will be mounted outside schools in London, the southeast and southwest of England on Thursday as well as Wales, and rallies are due to be held in Cardiff, Chichester, Bristol and Plymouth.
