London Underground has denied it will bring back Public Private Partnership schemes on the network. The RMT union claimed the current row over Tube Lines pensions indicated LU wanted to bring in private firms. But LU's managing director Mike Brown said it intended to keep control of Tube projects.
"There are no plans to repeat the PPP structures of the past. LU has recently taken the maintenance of the Jubilee fleet of trains back under our direct control. Our actions speak for themselves."
Maintenance staff on three tube lines are entering their third day of strikes today.
A strike affecting the Jubilee, Northern and Piccadilly lines goes ahead from 4pm.
Union bosses have forecast "widespread" disruption, as workers who maintain and upgrade tube lines go on strike next week.
