Today's news summary is a little early because I'm on holiday this afternoon. I'll be leaving Iain and James in charge... and, even though it's traditionally the "silly season", they'll have plenty to talk about in Wednesday's podcast.

Today’s podcast feature is a personal look at the cost of mobile ‘roaming’ in France.
