The number of bus journeys taken in London fell last year for the first time in 15 years, according to figures released by the Department for Transport.
More than two billion bus journeys were made in the city last year, which was a drop of 9.3 million compared with the previous year.
The Green Party said the fall was due to a hike in bus fares.
However Transport for London (TfL) said the fall was due to the Olympic Games.
