The Competition and Markets Authority (CMA) has extended the timescale of its investigation into Amazon’s investment in Deliveroo.

The deadline has been pushed back by eight weeks, to 6 August, although the CMA said it aims to complete the inquiry “as soon as possible and in advance of this date”.

The original deadline was Thursday (11 June), but the CMA said due to the nature of the investigation and the impact of coronavirus it would not be able to publish its report by then.

The CMA provisionally cleared the deal in April after Deliveroo warned it would have to cease operations without the cash injection.

Amazon was the lead investor in Deliveroo’s $575m funding round, announced in May last year.

Its stake, thought to be worth about $500m, has been frozen by the regulator as it conducts an investigation into alleged competition concerns raised by the deal.

Just Eat and Domino’s Pizza are among the companies that have written to the CMA and expressed concerns about the deal being allowed.
