London Underground weekend closures: Tube and Overground changes on July 24 and 25
There are planned closures across London's transport network this weekend - and there could be last-minute disruption due to staff self-isolating.
Transport for London (TfL) has warned that like other businesses, it may be affected by staff absence.
This could mean some changes to service frequency or some short-notice service or station closures as a result, it says.

Already planned are closures on some lines at certain times on Saturday and Sunday (July 24 and 25), including the Circle, District and Metropolitan lines.
Customers must continue to wear a face covering on services and in stations for the duration of their journey unless they are exempt.
This includes the Tube, bus, tram, DLR, London Overground and TfL Rail networks, Dial a Ride Services, the Emirates Air Line and the Woolwich ferry.
Most Tube services run until approximately 1am and night buses are still operating. Night Tube and Night Overground services are not running.
