Hundreds of thousands of pupils face a delay returning to many primary schools in England due to high rates of coronavirus.
The government is implementing a “contingency framework” in areas with very high rates of incidence or transmission of the virus – in many London boroughs and across the South East.
Children of key workers will still be able to attend, and early years provision will continue.
The framework says where primary schools need to, they should use remote education – by teaching online.
The closure of primary schools will be reviewed after 13 January and by 18 January, Boris Johnson has said.
The list of areas affected in London are:
Barking and Dagenham
Barnet
Bexley
Brent
Bromley
Croydon
Ealing
Enfield
Hammersmith and Fulham
Havering
Hillingdon
Hounslow
Kensington and Chelsea
Merton
Newham
Redbridge
Richmond-Upon-Thames
Southwark
Sutton
Tower Hamlets
Waltham Forest
Wandsworth
Westminster
Schools in 10 London boroughs will remain open under government plans. London is under tier-four restrictions following a spike in Covid-19 cases.
