Tommy Sheridan - who is he? Well, if you live outside Scotland you might not really know. But if you live in Scotland or are Scottish, you may well have been glued to your sets/PCs/newspapers/phone to home!
Mr Sheridan is, for the unitiated, a Scottish politician who is currently involved in a defamation trial which includes allegations of sex and swingers' parties. It makes for a heady mix; but at what point does a story of interest to one part of the UK move into the wider national arena?
It's a hard question and I'm afraid there's not a one-size-fits-all answer.
In this case, we knew we would do the biggest story in Scotland at the end of the trial.
But then today we thought it might be good to introduce those non-Scotland viewers to it before then, and as Mr Sheridan is actually questioning his own wife in the witness box today (he has fired his top QC) it was a great opportunity.
Here's a flavour of the proceedings:
The politician, who has described himself as teetotal, later questioned her about claims he had drunk alcohol. Mrs Sheridan replied: "You would not know one end of a wine bottle from the next.
"If I had read tea but wine... ridiculous, absolutely ridiculous."
Mr Sheridan asked his wife if she believed the women who had given evidence had been telling lies. She replied: "Total, utter rot."
But more generally, we look for a national resonance to a story. That can be the characters involved; or the story can illustrate an issue that's equally relevant outside Scotland, England, Lancashire or wherever. And sometimes its simply a cracking good story with no national resonance but one that will interest all viewers.
There have been times when we've of course not reported a local story nationally quickly enough. And I'm sure there will be more. And there will always be Scots who say news about the English and Welsh NHS is irrelevant to them and vice versa. Tricky business this.
