LOS ANGELES AP – Regulators in the U.K. and U.S. appear likely to impose conditions on the merger of concert promoter Live Nation Inc. and ticket-selling giant Ticketmaster Entertainment Inc. now that British authorities came out against the deal Thursday.

The U.K. Competition Commission said that combining Ticketmaster and Live Nation “could severely inhibit the entry of a major new competitor, CTS Eventim, into the U.K. ticketing market.” The British regulators have until Nov. 24 to determine what actions to take.
