Delays on the London Underground because of overcrowding have reached a five-year high, according to new figures obtained through Freedom of Information requests.

The figures showed there were 237 delays in 2014/15 because of overcrowding, compared with 153 in 2010.

The numbers are based on two separate FOI requests - one from the Greater London Assembly transport team of the Liberal Democrats and an earlier one from LondonLovesBusiness.

The year is calculated from March to April.

The worst offender over the last year was the Victoria Line - delayed 60 times due to overcrowding - but the Jubilee and the Northern Line were close behind.
