But as the Government urges all pupils across England to return to school for the autumn term, it has issued a new set of guidelines which the Department for Education says applies to private schools too.
This means that in theory, Kate and William could face a fine if they fail to send George and Charlotte back to school.
Outlining the new guidelines about schools reopening, the Government website states: “It is our plan that all pupils, in all year groups, will return to school full-time from the beginning of the autumn term.
“This guidance is intended to support schools, both mainstream and alternative provision, to prepare for this.”
“It applies to primary, secondary (including sixth forms), infant, junior, middle, upper, school-based nurseries and boarding schools.”
