London's congestion charge could rise by 15%. Transport for London is considering an increase from £10 to £11.50 on the standard daily charge.
Transport for London says the daily charge has not risen since 2011. Increasing it would generate an estimated £84 million of additional revenue by the end of 2017/18.
