Gig economy companies, including Uber and Deliveroo, have faced at least 40 major legal challenges around the world as delivery drivers and riders try to improve their rights.

The analysis of 39 employment cases, and seven linked cases on matters such as competition law, covers legal action in 20 countries including Australia, Chile, Brazil, South Korea, Canada and across Europe.

The cases have been brought by gig economy workers seeking access to basic rights, such as minimum wages and sick pay.

Put together by the International Lawyers Assisting Workers Network of more than 600 lawyers from at least 70 countries, the report highlights a string of court rulings in favour of drivers including in Italy, where authorities have fined Uber Eats, Glovo, Just Eat, and Deliveroo €733m (£628m) for misclassifying 60,000 couriers. That case is being appealed against.
