Uber faces legal threat from union over London licence

GMB says it will seek judicial review if Transport for London does not guarantee more rights for drivers

Uber has come under further pressure in London after a union threatened legal action if the capital's transport authority renews the taxi app's licence without guaranteeing more rights for drivers.

In a legal letter sent this week, the GMB union warns Transport for London (TfL) that failure to impose conditions which guarantee income for Uber drivers while limiting their number in the city and the hours they can work would "breach the relevant standards of reasonableness and would accordingly be unlawful".
