The Conservative group on the London Assembly has released a report suggesting Tube stations or Tube lines should be sponsored. They say the extra income from sponsorship could allow fares to be frozen.
It would mean that stations would have their names changed by adding a brand name. The Conservatives carried out a poll which found that 74% of Londoners believe Transport for London should expand sponsorship if it was used to cut or reduce fares.
