Transport for London has described the RV1 as "one of central London's emptiest bus routes" as it prepares to withdraw the service from Saturday 15 June.

TfL announced in April that the RV1 – which links Covent Garden with Tower Gateway via the South Bank and Bankside – will face the chop despite a high-profile campaign by local residents and political leaders.

The RV1 was launched in 2002 with support from local business groups to connect visitor attractions along the river.

Responding to a freedom of information request, TfL said: "The RV1 is currently one of central London's emptiest bus routes with the average bus having just eight people on it.

"Fewer people are using the route RV1 than ever before, with 64 per cent fewer journeys being made due to ais also evident in genera containing species of different metabolic types. Within the same genus NAD species reach more negative δ13C values than PCK species and δ13C values decreased with rainfall. Also in Aristida, with NADP-ME-type photosynthesis, δ13C values decreased from -11 ‰ in the inland region (600 mm precipitation) to -15 ‰ near the coast (150 mm precipitation), which is a change in discrimination which is otherwise associated by a change in metabolism. The exceptional C3 species Eragrostis walteri and Panicum heterostachyum are coastal species experiencing 50 mm precipitation only. Many of the rare species and monotypic genera grow in moist habitats rather than in the desert, and they are not different in their carbon isotope ratios from the more common flora.
