Primary schools in Hertsmere, including Potter Bar and South Mimms, are one of the 49 areas in England where primary schools will not be able to reopen until January 18.

Pupils will need to switch to remote learning for all but vulnerable children and those of key workers.

The other affected areas in Hertfordshire are Watford, Broxbourne and Three Rivers.

Gavin Williamson, the Secretary of State for Education, announced yesterday that all other primary schools are set to reopen as planned from Monday, January 4, with secondary schools and colleges staggering the start of term up to Monday, January 18.
