Margaret Hodge has called on the Mayor of London to freeze fares next year.

The Barking MP signed a Commons early day motion asking Boris Johnson not to increase the cost of travel in the capital for 2014.

She said: “London’s commuter fares are the most expensive in the world. I was shocked when I learned that Transport for London, which is responsible for our buses and trains, is sitting on a surplus.

“At a time when wages are falling and household bills keep rising that’s just not acceptable.

TfL denied it had a surplus and said that “every penny” is invested into the transport network “to deliver a better service.”.

Since 2008 the cost of a single bus journey in London has increased by 56 per cent and a zone one to six travelcard is £400 a year more expensive.
