The Independent Workers Union of Great Britain (IWGB) had tried to represent a group of Deliveroo riders in order to negotiate pay and conditions with the company.

The union was first refused permission in 2017 on the basis that riders were not "workers" under UK labour law and it has since mounted a number of appeals.

The IWGB took its case to the UK's highest court in April, arguing that it was an unlawful interference with riders' human rights to deny the IWGB's application to be recognised by Deliveroo for collective bargaining.

But the Supreme Court unanimously dismissed the IWGB's appeal in a ruling on Tuesday.

Announcing the court's decision, Judge Vivien Rose said Deliveroo riders do not have an "employment relationship" with Deliveroo and were not entitled to compulsory collective bargaining.
