London Underground drivers began a 24-hour strike at midday today, causing widespread disruption to the city's subway system. The walkout is being conducted by members of the Rail, Maritime and Transport (RMT) union.

The strike centers on disputes over working conditions and hours, with drivers expressing concerns about current workplace arrangements. Service has been stopped on two lines, with additional delays expected across the network.

This represents the first of two planned 24-hour walkouts scheduled for this week. The RMT union organized the coordinated action as part of ongoing negotiations with Transport for London.

London commuters are facing significant delays and are being advised to seek alternative transportation methods. The disruption comes during a busy period for the capital's transport network.

Transport officials have not yet announced when normal service is expected to resume. The second planned strike later this week threatens to extend the disruption for London's millions of daily tube users.
