Original deadline has been moved back to 7 December.
The Competition and Markets Authority (CMA) has extended the deadline for its investigation into the proposed £15 billion merger between Vodafone and Three UK.
The CMA probe is now set to conclude eight weeks later than originally scheduled, with a new deadline of 7 December.
In a statement, the CMA, said: “The inquiry group now considers that it will not be possible to complete the investigation and to publish its final report within the revised reference period. The inquiry group aims to complete the inquiry as soon as possible.”
The CMA decided to refer the merger for a full investigation after setting the companies an April deadline to address its competition concerns, which they failed to meet.
