WWE's attempted monopolisation of the UK market shouldn't really come as a surprise to anyone who has tracked the promotion's business tactics over the past three decades.
In Vince McMahon's eyes, Britain is his market, and that's true whether or not companies like PROGRESS are earning rave reviews, ICW are selling thousands of tickets in local arenas every year or ITV are attempting to bring back World of Sport.
