London commuters are this morning enduring major disruption on three Tube lines.
The Metropolitan, Hammersmith and City and Circle lines are all operating with severe delays.
It is due to a faulty train at Euston Square, which engineers are trying to fix.
It means there are severe delays between Baker Street and Aldgate on the Metropolitan line.
On the Hammersmith and City line, the disruption is on all westbound services, while the anti-clockwise route on the Circle line has been hit.
