Members of the RMT transport union will demonstrate outside Kings Cross this morning to mark the 25th anniversary of the fire that devastated the underground station.

Union leaders have organised the event to highlight what they describe as the continued need for a fully staffed and safe tube network.

They believe safety will be threatened by measures planned by Transport for London, and have claimed the organisation wants to “impose an unattended network.”

Speakers will include RMT general secretary Bob Crow, Matt Wrack, the Fire Brigades Union general secretary, and politicians Andrew Dismore, Frank Dobson and John McDonnell.

Mr Crow said: “Due to a culture of complacency and systemic failure, 31 people lost their lives in the fire at Kings Cross underground station.

“We are marking the event with a public demonstration to send out the message that never again must the London Underground be dragged back to the same catalogue of complacency and failures which led us to Kings Cross.

“RMT, our trade union colleagues, politicians and the community will be calling on Boris Johnson and his officials to end once and for all the threatened cuts to station and platform staffing levels, the cuts to maintenance schedules and the persistent threat to bring in driverless trains, threats that Boris Johnson raised once again at the Tory Party conference only a few weeks ago.

“All of that posturing and corner-cutting has to stop and the safety regime introduced after Kings Cross must be both protected and developed to meet the modern challenge of ever greater tube passenger numbers.”
