Secondary ticketing site Viagogo has been labelled “a blot on the landscape” by the ticketing director for forthcoming West End musical Hamilton.

Keith Kenny, sales and ticketing director of Cameron Mackintosh, was giving evidence this week to a Culture, Media and Sport Committee on misuse of the secondary ticketing market, at which Viagogo did not show.

Cameron Mackintosh took significant steps earlier this year to stop online ticket touts from buying large numbers of Hamilton tickets and reselling them at extortionate prices. Despite this, seats for Hamilton are now listed for up to £6,000 each on the secondary ticket site Viagogo.

The measures put in place for ticketholders include in-person box office collection, photographic identification and presentation of the original card used for purchase. Kenny also stressed that there were other plans to prevent on-the-door touts, but said they “would not be the same every evening”.

Kenny described Viagogo as a “blot on the landscape” as they are the only secondary ticketing site currently listing Hamilton seats. He went on to say that Cameron Mackintosh had written to Viagogo bosses to inform them that reselling was prohibited and could result in tickets not being honoured, and requesting the removal of the Hamilton listings.

“Ultimately, our terms and conditions say ticket reselling is forbidden. If you look at the way that glossy, sneaky site is constructed, they’ve gone an awful long way not to be compliant in the way they’ve built their site,” Kenny said.

Committee member Nigel Huddleston said: “Viagogo have clearly shown a lack of respect to parliamentarians and by extension the British public, and I think we need to be very angry with that.”
