There is a promotional video currently on the website of Marcus Evans Group with specific reference to the contract of their THG ticketing subsidiary with the Olympic Council of Ireland (OCI) for the London 2012 and Sochi 2014 Olympics. The video features OCI president Pat Hickey, pictured above with Grozny/Aleppo bomber Vladimir Putin. Hickey is now being detained in Rio de Janeiro accused of ticket touting. Anyway, at around 2m40s in the video, Hickey discusses the length of the ticketing concession and says with reference to what happens after Sochi --
we will reassess for the future but we would be very happy for Marcus Evans Group to have the first option of refusal if you like or takeup and I think that it will work very well together between both parties
Why they didn't get the 2016 concession and what actions that might have triggered is integral to the Rio authorities' case.
