This is the embarrassing moment that the country's most senior policeman didn't know the number of the anti-terror hotline.
Sir Bernard Hogan-Howe, the Metropolitan Police Commissioner, was told by a caller that it was too difficult for people to report alleged terrorists.
He told them they could call the anti-terror hotline, but then admitted he didn't actually know what the number was.
When asked what the number was, he stuttered: "Erm, at this second, I must admit I haven't got it with me.
"I know it's an 0800 number, so it's a free number."
Nick Ferrari stopped him to say that is the point - shouldn't we all know this number?
Sir Bernard added: "Every other time I've been in, I've mentioned it, so this is the first time I've not actually mentioned it.
"The point, should it be a clearer number is a good one. I think that's something we can take away and have a look at.
"The broad point, I think people know that they can ring 101, you can ring the Crimestoppers number on 0800 555111 and you can make sure that the police get the information they need."
