Labour's malcontent MPs now busily undermining Jeremy Corbyn should heed the words of Tom Watson.

The party deputy leader’s support and loyalty to Corbyn shames the self-indulgent grumblers who backed unsuccessful candidates in the leadership campaign and provides a lesson in how to behave to these moaning bad losers.

Every gripe, attack and disloyal outburst from sulking MPs weakens the Labour Party and is music to the ears of Conservatives, Ukip, SNP and other other rival forces that would happily consign the party to the dustbin of history.

Corbyn has earned an opportunity to prove that he has what it takes.

He needs a successful week and a keynote speech that makes him look and sound a leader.

Yes, he must reach out to critics and appeal to the country at large.

Delaying a decision on an issue as contentious as Trident until next year, or the one after, would be sensible.

But British politics is in flux.

David Cameron will soon be gone and the Tories could rip themselves apart over Europe.

Nobody can predict a future yet to be won.
