More than 20 Labour MPs signed a Commons motion condemning London public transport fares, urging mayor Boris Johnson to freeze increases next year. The motion says:
Transport for London has reported unbudgeted operational surpluses for the previous three years and is showing evidence of regularly under-anticipating fares income and overestimating other expenditures
(We) call on the mayor of London to use his discretion to freeze fares at RPI (retail price index) for 2014, easing the pressure on ordinary Londoners during the current cost of living crisis.
