A very warm welcome to this Sunday sermon, Britain's favourite Sunday sermon.

And what a week we've had amongst all the political chaos and noise, the anxiety, the fury about the latest immigration numbers, the calm, reassuring presence of the top people in the Home Office, in front of the Home Office Select Committee.

Just imagine for a moment, though, that you're the managing director of a division of a big company, you've had a few problems, things are not going very well, and you've been hauled up to see the directors and the shareholders of the business, frankly, to explain yourself, to explain what's going wrong, how you're going to put it right.

Surely, you're going to do a bit of work, a bit of preparation.

You're going to jet up on all the answers, You're going to come up with some reassuring solutions. You'll bring some people with you to help you with some numbers and things, but you are going to be well briefed because you know that frankly, if you don't perform, if you don't give some confidence to your directors, to your shareholders, then you're going to be held accountable. You could be fired. You could be literally out on your arse for incompetence, for negligence, for failing to do your job properly.

That's in the real world, yes, the world of the private sector that has to perform or fails.

Surely it should be the same in the public sector. I mean after all we the taxpayer are their customer and the elected representatives, the ministers, the Secretary of State are the equivalent of their directors and we the taxpayers or the shareholders represented by MPs for example on this Home Office Select Committee.
