Top UK fund refuses to invest in Deliveroo amid City concern over riders' rights

Aviva Investors cites lack of basic workers' rights as investment risk' ahead of flotation

One of the UK's top fund managers is to boycott the stock market float of the meal delivery firm Deliveroo next month, amid growing disquiet in the City over the company's treatment of delivery workers.

Aviva Investors said on Wednesday it had turned down the chance to invest in Deliveroo's 9bn initial public offering. Aberdeen Standard, another of the UK's biggest investors, has also expressed concerns about Deliveroo's employment practices, the Guardian understands.
