 In 1985 the operation of some bus services was put out to tender for the first time and, for a number of years, buses bearing a variety of different colour-schemes operated alongside those still operating in the traditional red livery by operators such as Armchair Passenger Transport, Boro'line Maidstone, Capital Citybus, Grey-Green, Harris Bus, Kentish Bus, London Buslines and Metrobus.In response to the competition, LRT established low-cost business units Bexleybus and Westlink.The variety of liveries was found to be confusing to tourists and non-Londoners expecting to find red-painted buses and, after lobbying from the tourist board, in 1997 it became a requirement when contracts were retendered that bus liveries be predominantly red.
