The UK's Competition and Markets Authority (CMA) has the ticket sellers from integrating their businesses so it can investigate the proposed merger.
StubHub and Viagogo announced the planned US$4bn merger in November. But the CMA says it has “reasonable grounds for suspecting that it is, or may be the case, that arrangements are in progress" already.
Senior representatives of StubHub and Viagogo must report to the CMA fortnightly to prove they are still distinct businesses. The companies must also maintain separate sales and brand identity.
