YES - Douglas McArthur, Managing consultant, Planning for Results
A trade body's ability to lobby regulators and government is much stronger when it represents all the members of an industry sector - as the RadioCentre and its predecessor, the Commercial Radio Companies Association, did.
So yes, lobbying will be hampered, but the real question is: "How seriously?" I don't think it is at all surprising that the RadioCentre can't get the whole industry to agree on major investment policies.
Commercial radio is a diverse industry - stretching from Global to very small stations - so it is a big job to get unanimity on topics such as DAB and analogue switch-off.
When I ran the Radio Advertising Bureau, we focused on one objective for the commercial radio industry - growing the ad revenue. It is easy to get all parts of the industry to agree with that, because every station would like more money, and very much easier than trying to get unanimous support for analogue switch-off.
NO - Steve Orchard, Chief executive, Quidem
The RadioCentre still represents the overwhelming majority of commercial radio stations - from bijou Rugby FM to mighty Classic FM. Both UTV and UKRD want to remain shareholders, so perhaps this is decree nisi rather than decree absolute.
The RadioCentre still commands unanimity in critical areas, such as the RAB, which drives national customer relationships; commercial radio's relationship with the BBC; and the drive to deregulation.
As for digital migration, there are many unanswered questions and we should thrash out differences between ourselves. If minority positions emerge, so be it - there still remains more of a common purpose than not.
We are a small sector facing very complex issues - but, thankfully, despite the resignations, we still have a potent trade body to deliver our messages with the strongest impact.
NO - Ralph Bernard, Chairman, Classic FM
Commercial radio has suffered countless internal wrangles in its 36-year history. I'm sure the forerunner of the RadioCentre never rescinded one of its most bitterly argued decisions - taking a formal position against national commercial radio.
That decision divided opinion, but didn't fracture the solid base of common purpose. Unity has always been the most effective tool, recognised as a strength by regulators and government.
Dirty linen should never be washed in public and, since 1973, commercial radio has usually been good at keeping its arguments behind closed doors. I'm sorry UTV has taken its decision. Scott Taunton, the chief executive, has an excellent radio pedigree, but in this matter perhaps he has been unwise.
The RadioCentre continues to represent the substantial majority and will lead the debate in important places. It carries credibility, weight and has the experience to handle the ship in these turbulent waters.
YES - Simon Blackburn, Business director, MPG
One of the great strengths of the RadioCentre has been its ability to represent the radio industry so admirably. Other industry bodies have looked on enviously, struggling to deliver the same degree of support and value.
There is a difficult debate between evolving the commercial industry from a technological perspective and satisfying the requirement for local stations to serve local communities, and this has reached a tipping point.
Sadly, the 2015 planned switchover from analogue to digital, supported by the RadioCentre, is threatening the long-term survival of many local stations.
The RadioCentre says its role is "to maintain and build a strong and successful commercial radio industry". This small sector is at its most powerful when speaking with one voice, so the withdrawal of UTV, UKRD and TLRC cannot be good news.
