Stena Line's acquisition of DFDS Seaways Irish Sea services in December, has now been referred to the UK's Competition Commission by the Office of Fair Trading (OFT).

The £40m ferry deal for two routes, Belfast-Birkenhead (run by two chartered ro-pax ferries) and the Belfast-Heysham freight-only service, included two 114-trailer capacity vessels.

The Competition Commission is expected to submit its findings by the end of July while the Irish Competition Authority is also still investigating the merger. To read more about this, click the BBC report here.
