London Tube strikes cause travel chaos

The London Underground network is grinding to a halt as militant workers protest against proposed changes to working conditions and hours.

Transport for London has warned passengers to check before traveling, as several lines are expected to have little or no service.

The strikes have drawn criticism from business leaders who fear a significant impact on the city's hospitality and retail sectors.

Meanwhile, political tensions have flared as the Green Party is accused of siding with the union over commuters, deepening the instability in the capital's transport infrastructure.
