Quarter of all tickets are resold; LEISURE.
AS many as a quarter of tickets to popular music, theatre and sporting events end up on secondary ticketing websites, according to an investigation.
Tickets appearing on sites such as Viagogo, GetMeIn!, Seatwave and StubHub as soon as any major event goes in sale is now "the norm", Which? found.
It found that 26 per cent of tickets for comedian Jack Whitehall's upcoming Eventim Apollo show ended up on four secondary sites, as did 17 per cent of tickets for Lady Gaga at the O2 Arena in London and 15 per cent of tickets for the first night of the BBC Proms at the Royal Albert Hall.
Which? also found consumers are still not getting the ticketing information required by law when buying from secondary websites.
It also found that half of people (49 per cent) who bought tickets on these sites thought they were official sellers.
Alex Neill, of Which? said: "People are finding themselves having to buy tickets through secondary sites more and more, and yet many struggle to find the basic information required by law.
"There needs to be more transparency within the secondary ticketing industry."
