The government has published its safety plans for England's return to school in September - built on the principle of keeping classes or whole year groups apart in separate "bubbles".

Schools will have testing kits to give to parents if children develop coronavirus symptoms in school.

Mobile testing units may be sent to schools which have an outbreak.

The education secretary said there must be a "concrete determination" to get pupils back to class.

"By working together we will make sure that their hopes and dreams for the future are not to be knocked off course," Gavin Williamson told journalists.

"We cannot sit back and... just say that children are not going to go back to school."

He said a "system of control" would "minimise the risk" from Covid-19.

Children will not be taught a "watered-down" curriculum, he added - insisting that it will be "world-class ".

Labour's shadow education secretary Kate Green accused the government of being "asleep at the wheel" over getting children back into school full-time.

Head teachers said it would be "mind-boggling" to try to keep groups of pupils apart all day in school.

What are the new rules for autumn?
The safety plans issued by the Department for Education say that "given the improved position, the balance of risk is now overwhelmingly in favour of children returning to school".

The return will be based on separating groups of children into "bubbles" and minimising contacts between them, rather than social distancing.

It will mean:

Grouping children together in groups or "bubbles", a class in primary and year group in secondary
Avoiding contact in school between these groups, with separate starting, finishing, lunch and break times
Attendance compulsory with the threat of penalty fines
Test and trace in place for schools
Regular cleaning of hands, but masks not expected for pupils or staff
Those with symptoms told to stay out of school
No big group events like school assemblies and arranging classrooms with forward facing desks
Separate groups on school buses and discouraging the use of public transport
Pupils will be expected to continue with all their GCSEs and A-levels
If you could fast forward to September and schools in England were not opening there would be outrage from parents.
