Ticketmaster in the UK may have misled fans and broken the law during Oasis ticket sales, the competition watchdog has said, writes Tom Lawrence.

Thousands waited for hours in virtual queues last year to get tickets for the band's reunion shows, only to find costs jumped in a 'dynamic pricing' scheme.

Ticketmaster sold 'platinum' tickets for nearly 2.5 times standard price but did not explain they had no added benefits.

The CMA launched an investigation into Ticketmaster last September to examine if it engaged in "unfair commercial practices".

It was concerned that the company, which sold more than 900,000 Oasis tickets, may have breached consumer protection law.

The CMA is calling for Ticketmaster to change how it labels tickets and informs customers.

Hayley Fletcher, CMA's interim senior director of consumer protection, said: "We're concerned Oasis fans didn't get information they needed or may have been misled into buying tickets they thought were better than they were."

Last year Oasis said they were "not aware" the system would be used and the decision was made by Ticketmaster, promoters and management.

Ticketmaster has been contacted for comment.
