Any other Labour leader would have gone by now.

Since Sunday more than 50 members of Jeremy Corbyn’s shadow cabinet have resigned.

His MPs have overwhelmingly voted that they have no confidence in his leadership.

His leader in Scotland has effectively called on him to stand down.

And the biggest-selling Labour newspaper in the UK, the Daily Mirror, has deserted him.

But Mr Corbyn is no ordinary Labour leader.

None before were elected under the new system which saw tens of thousands join the party just to vote for him.

He has never been afraid to stick to his own line.

That much can be seen by the fact that in his decades on the backbenches he voted against his own party more than 500 times.

He is also not easily swayed by what others think.

That is again seen in his voting history, but there are many other examples.

He was condemned for meeting Gerry Adams at the height of the Troubles, but he did it anyway.

He once described Hamas and Hezbollah as "friends".

And yet, for all his single-mindedness, Mr Corbyn is not just one man, he is a representative of an entire section of his party.

And the left of Labour have not spent decades wanting to take over the party just to give up now.

In the midst of it all there was farce.

Labour invited the television cameras in to a meeting of the new shadow cabinet, still missing a shadow Scottish Secretary after the party’s one MP north of the Border stood down.

But Mr Corbyn was caught on camera telling one of his closest aides that his did not think the move was such a good idea.

So the television crews were asked to stop filming.

When they returned the MPs sitting on Mr Corbyn’s left and his right had changed.

Significantly they no longer included Tom Watson, his deputy leader, who on Monday told him that MPs no longer had any confidence in his leadership.

While the broadcasters did a double take, Mr Corbyn himself carried on as if nothing had changed.

The scene was a metaphor for his current policy.

And one that puts him at loggerheads with most of his MPs.
