The British government currently has no plans to restrict travel in and out of London or to close down the capital’s underground tube service, Prime Minister Boris Johnson’s spokesman told reporters Thursday.

Transport for London (TFL) said Wednesday that it had plans to close “until further notice” up to 40 tube stations that do not interchange with other lines.

Johnson is meeting Thursday with London mayor Sadiq Khan to discuss plans for the capital, according to City Hall.

The meeting comes amid widespread speculation and concern that London could be placed under lockdown.

All the nations of the UK announced school closures starting this weekend “until further notice." Politicians are suggesting that schools might not resume during this academic year.
