Members of the Rail, Maritime and Transport (RMT) union began a five-day strike that brought central London to a near standstill on Monday, disrupting Underground services, increasing road congestion and prompting organisers to cancel major events.

Entrances to multiple Tube stations were closed and bus drivers were reported to have turned away passengers as surface services sought to contain numbers amid the disruption. Demand for cycle-hire schemes, black cabs and ride-hailing services surged, while motorists faced substantially longer journeys due to heavier traffic and existing roadworks. The action coincided with the third anniversary of the King’s accession to the throne, when a 41-gun salute was fired over Hyde Park.

Organisers of Coldplay’s planned concerts at Wembley Stadium announced cancellations after concluding they could not ensure safe onward travel for about 82,000 ticket-holders. Event promoters and transport operators said the scale of the disruption made delivering and dispersing large audiences unsafe.

The RMT said its members were striking over pay, hours and working conditions. The union’s demands reported during the dispute include calls for a 32-hour, four-day working week and further pay increases. The union has also sought a substantial discounted rate for rail travel for its members. Negotiations have been under way for nine months, following an earlier agreement in which the RMT accepted pay rises of up to 6.6% last November.

Industry groups and business representatives warned of significant economic impacts across the capital. Some estimates put lost business during the strike period in the hundreds of millions of pounds, with hospitality and retail among the sectors most at risk from reduced footfall and cancelled bookings.

The walkout coincided with the annual Trades Union Congress (TUC) gathering in Brighton. Trade union leaders attending the conference expressed concern about the pace and direction of national employment policy and about any changes they believe could make it easier to restrict strike action. Membership of TUC-affiliated unions has declined in recent decades, a trend commentators note has shifted the balance of union strength toward the public and quasi-public sectors where membership remains concentrated.

Transport for London (TfL) services operate under a complex mix of labour agreements, rolling maintenance and infrastructure constraints. Driverless and automated systems already operate on parts of the capital rail network, including the Docklands Light Railway, but the wider rollout of such technologies involves regulatory, technical and budgetary considerations that have featured in long-running industry discussions.

Government ministers and city officials have faced calls from business groups and commuter organisations to resolve the dispute quickly. Prime Minister’s Office and City Hall statements on the strike were not immediately available at the time of reporting.

Union leaders said the industrial action is intended to press employers to make further concessions after prolonged talks. Transport operators and event organisers said they would continue contingency planning for the remainder of the strike period and urged passengers to check services and travel only if necessary.

Talks between unions and employers are expected to continue while the walkout proceeds. Officials and stakeholders will assess the immediate economic and operational impacts once services resume and planners are able to quantify cancellations and revenue losses tied to the disruption.
