Four teenage boys have worn skirts to school in protest at being disciplined for wearing shorts on the hottest day.
The year nine students at Longhill High School in Rottingdean, East Sussex, were among about 20 boys who wore PE shorts instead of trousers on Tuesday.
Some were sent home, and others kept in isolation and excluded the next day.
When the four boys turned up in school skirts on Thursday, head teacher Kate Williams said they could “wear any part of the agreed school uniform”.
The mother of 14-year-old Michael Parker, who was one of the group, said three of the boys were initially told to remove the skirts, but all four of them kept them on.
Angela Parker said they wore them to school again earlier, and were joined by a further 10 boys.
The PE shorts worn by the boys on Tuesday were an official part of the uniform, bearing the school logo.
