Boris Johnson has been urged to deliver on a commitment to introduce a weekly cap on Oyster pay as you go fares in 2015.
The commitment was made last year in a letter to Liberal Democrat London Assembly Caroline Pidgeon who has previously criticised the decision to introduce weekly caps on contactless fares before Oyster.
Transport for London says a system upgrade is needed to allow Oyster to support the weekly cap, and the Mayor has said it would be wrong to delay introducing the cap on contactless until the upgrade is complete,
In a letter to Ms Pidgeon dated 31st July 2013, the Mayor said the necessary work would be carried out in 2015.
Speaking on Wednesday, Ms Pidgeon said: “Contactless payment is a useful form of payment for some people, but people who use Oyster pay as you go should be never be penalised, especially as some people without access to a bank account have to use Oyster.
“Over 15 months ago the Mayor made a specific commitment that a weekly cap on Oyster pay as you go would start from 2015. It is time that the Mayor finally honoured that commitment and ensured that the cheapest fares truly can be obtained using Oyster.”
