Hundreds of Uber drivers and other ‘gig economy’ workers are to stage a protest march through London on Tuesday.
This is to be ahead of a Court of Appeal hearing linked to the employment rights and status of drivers working through the app.
The demonstration, which is part of nationwide action, has been named "rise of the precarious workers".
The Independent Workers Union of Great Britain, which is involved in the case, expects it to be the biggest ever protest of its kind in the UK.
