Labour MP tired and emotional in Commons

In my other article today I made reference to the unparliamentary behaviour of the Labour MP for West Bromwich East, Tom Watson.  I really do have to wonder whether the gentleman was 'tired and emotional' at the time.  Anyway, here's the video:

Labour MP, Tom Watson, losing his cool in the chamber - tired and emotional, perhaps?

One thing you might notice here is that Mr. Watson doesn't even see fit to apologise to the Education Secretary for his outburst, choosing instead to withdraw the word 'pipsqueak' because he had to.

And as for Mr. Gove's response?

I am grateful to the hon. Gentleman for his question; it gives me the opportunity once again to apologise to his constituents and to other parents and teachers in Sandwell for the confusion that was caused by the mistake that I made on Monday. I understand the passion that he brings to the issue, and I understand how hard he fights for his constituents. I shall be very happy to go to West Bromwich and apologise to those who have been misled by the mistake that has been made. I am more than happy to do so. As I said earlier, the mistake was mine and mine alone, and I am happy to acknowledge it.

Rather restrained, don't you think?
