London mayor Sadiq Khan was today under pressure to abandon his controversial fares freeze because of the soaring cost of Crossrail.
Delays to the project have forced Transport for London to write off £600m in lost income from fares and advertising.
The partial fares freeze was a key promise in the Labour mayor's 2016 election manifesto but it left a £640m hole in TfL's budget.
A new business plan published by TfL today calls for a fares increase of inflation plus one per cent from 2021
TfL's shaky finances also mean some long-awaited uprgades to stations including Camden Town and Holborn will be postponed and a planned upgrade to Piccadilly Line signals is on hold.
City Hall said the mayor's fares policy after 2020 would be announced in his next election manifesto.
Crossrail was yesterday given another £2bn bailout taking the total cost of the project to £17.6bn. The opening date was also postponed again.
Transport bosses suggested the east west rail link would not be ready until 2020.
