The UK’s Competition and Markets Authority (CMA) has confirmed that it is investigating the proposed merger between operators Flutter Entertainment and The Stars Group.

The CMA has begun a merger inquiry to consider whether the £10bn merger will create a “substantial lessening” of competition within the United Kingdom for goods or services.

To assist it with its assessment, the CMA is inviting comments on the transaction from any interested party until 18 February.

Written representations about any competition or public interest can be sent to principal case officer Sophie Mitchell.

The CMA’s decision on the transaction is expected to be announced on 31 March.

Shares in Flutter Entertainment plc (LSE:FLTR) were trading at 8,598.00 pence per share in London Wednesday morning, while shares in The Stars Group (TSX:TSGI) closed at CAD$31.88 per share in Toronto Tuesday.
