Jack Irvine Executive chairman, Media House
"I don't think we need a Scottish Six. No-one in London is interested about what's happening in Aberdeen or Fife, in the same way we don't care about Manchester or Birmingham. It's selfish to think they should get more coverage. We already have BBC Newsnight Scotland where MSPs are boring us to death. We know what's happening in our own back yard.

"I feel sorry for those who seem confused by coverage on teachers or health and think it affects Scotland when it doesn't.

"It's ludicrous to have a Scottish Six, we don't need something that insular. When I come to London, I might take a Herald into the office and it's treated not just like a paper from a different country, but it might as well be from a different planet - Londoners don't care."

"I think part of this problem is the producers of these news shows are not informed themselves, so what you are tending to get is producers opening bulletins, particularly national bulletins, with stories that relate to England and Wales but really have no relevance for Scotland. Typically, you are getting something about health matters or legal matters - for example, they will have an opening remark about children being vastly overweight, but these figures relate to England and Wales rather than to Scotland.

"It is quite often the case that things that are happening in England and Wales are not the same as matters happening north of the Border, so people do get confused by that.

"It seems to be that producers who are handling national bulletins don't really understand which matters are devolved and which matters are reserved, therefore the audiences themselves are not well educated.

"What we don't need is a Scottish Six or anything parochial of that kind looking at international events through tartan tinted spectacles. What we need is better education of the national based producers."

"The term is broadcasting not narrowcasting. Scottish politics is important and has to be covered well. But I would argue it may be less important than the global trends that shape Scotland. The Scottish Six is a trophy' that will always be argued over by politicians and news aficionados. I'm not sure it's as big an issue for viewers."

"Devolution seems to have entrenched the differences in many ways. It's hard to see Scotland adequately represented in the UK-wide news as well as Wales and most parts of England outside the London area.

"Having a separate political system, there's a need to reflect that adequately in Scottish broadcast news. I think we would have to welcome the BBC Trust's investigation into this and obviously it anticipates the findings of the Scottish Broadcast Commission which is also going to be looking at these questions. I think it's likely that what will come out of the Scottish Broadcast Commission is a renewed focus on the way in which journalism is performing both north and south of the Border, which will form a debate.

"I think what we're going to get is a wake up call from several quarters. I don't think network news does a good job of UK coverage as a whole, but I think we need to raise questions about broadcast journalism in Scotland."
