Unless direct evidence is found that Cumming made other trips to Durham (April 19th / May 10th, etc) he'll get away with this - as he has put together a story, whilst full of holes, will stand up. But, in answer to a direct question, he said he hadn't been outside the bounds of London, except to Chequers, since his return. If he is found to have lied over that - then he's toast. Otherwise, this will all fizzle out.
Must say, I'm a bit disappointed with the journalists. You'd have thought they they would have got together to ask a series of harder and harder questions, instead of just repeating basically the same question - sometimes really only making a point. They should really have asked things like 'how could a four-year old last five hours in a car without a stop', 'why Barnard Castle instead of round and round', 'why did you have to drive - couldn't your wife have driven you', and so on. They won't get another chance, and I think they missed their opportunity really.
