The London stage of the World Naked Bike Ride starts from six separate points around the capital tomorrow afternoon, with nude or semi-nude riders set to finish at Wellington Arch at Hyde Park Corner around 5.30pm.
Organisers claim the protest, which will cause disruption to roads in the centre of London, is aimed at raising awareness about the safety of cyclists while calling for action on climate change.
Participants have been urged only to strip naked until the demonstration moves off so they don't upset authorities.

"Feel free to undress in the UK at any other time of the year, as this will not have any impact on the WNBR."
Previous events in London and elsewhere in the world have seen cyclists coated in body paint, emblazoned with tongue in cheek messages including "No fumes" and "Burn bras not fuel".

"The finish area will not be a venue for prolonged naked socialising," organisers warned.
