The figures, covering the period 8 January to 4 February, show that the percentage of scheduled services was 97.1 per cent.

Average delays for the financial year to date - as measured by the number of customer hours lost to disruption - are at their lowest since 2003/04, when TfL took responsibility for the Underground.

This period is the sixth consecutive period where delays are down compared to the equivalent periods during the last financial year.
 
The latest figures also show accessibility improvements around the network, with more than 98 per cent of lifts available at LU stations during the period.

Work included returning Earl's Court to full step-free status, with lifts there returned to service four months ahead of schedule following a nine-month programme of works to increase lift reliability.
