Dua Lipa is among the dozens of musicians who have urged Keir Starmer to honour his pledge to protect fans from online ticket touts.

Coldplay, Sam Fender and Radiohead are among the artists whose fans have been fleeced or priced out of events by bots being used to buy tickets in bulk the moment they go on sale.

They are now leading calls for the Prime Minister to commit to price cap legislation in the next King’s Speech.

They have signed a joint statement, along with Which?, FanFair Alliance, O2, the Football Supporters’ Association and organisations representing the music and theatre industries, venues, managers and ticket retailers.

In the statement, the coalition said new protections are needed to “help fix elements of the extortionate and pernicious secondary ticketing market that serve the interests of touts, whose exploitative practices are preventing genuine fans from accessing the music, theatre and sports they love.”

It added: “For too long certain resale platforms have allowed touts to bulk buy and then resell tickets at inflated prices, forcing fans to either pay above the odds or miss out entirely. This erodes trust in the live events sector and undermines the efforts of artists and organisers to make shows accessible and affordable.

“Introducing a cap will restore faith in the ticketing system, help democratise public access to the arts in line with the Government’s agenda and make it easier for fans to spot illegal behaviour, such as ticketing fraud.”

The Labour manifesto promised stronger consumer protections and the government has since pledged to cap resale prices to shut out the online touts.

But more than a year after it first promised action, and seven months since its consultation on the issue closed, there has been no clear indication of when new laws will be introduced.

Oasis tickets for Wembley Stadium shows were listed for £3,498.85 on Stubhub and £4,442 on Viagogo. A seat for the Minnesota Vikings vs Cleveland Browns NFL clash at Tottenham Hotspur Stadium was listed for £3,568.39 on Stubhub, while a Coldplay ticket, also for Wembley Stadium, was £814.52 on Stubhub.

The most extreme example Which? found was a ticket for the All Points East festival in London’s Victoria Park, headlined by Raye, listed for £114,666 on Viagogo.

Lisa Webb, Which? consumer law expert, said: “Today’s joint statement makes clear that artists, fan organisations and consumers reject the broken ticketing market that has allowed touts to thrive for too long.

“The Prime Minister pledged to protect fans and a price cap on resold tickets will be a critical step towards fixing this industry, but he must commit to this legislation by including it in the next King’s Speech.

“Further reforms are also needed to ensure sellers actually own the tickets they advertise before listing them, that resale platforms ensure the identities of sellers and key information about a ticket are verified and that the new rules are effectively enforced.”

Which? found prolific sellers in locations including Brazil, Dubai, Singapore, Spain and the US, hoovering up tickets for popular events in the UK, before relisting them at vastly inflated prices on Stubhub and Viagogo.

A Government spokesman said: “This Government is fully committed to clamping down on touts and is going further to put fans back at the heart of live events. We have carefully considered evidence provided in response to our consultation earlier this year and will set out our plans shortly.”
