This today from Dan Hodges:

"the idea that once Corbyn goes, Labour's problems go with him. The shadow Shadow Cabinet – Chuka Umunna, Dan Jarvis, Lisa Nandy, Clive Lewis, Yvette Cooper – are now playing an elaborate game of Ring A Ring O' Roses. Just hide and wait and pray for the plague to pass.

There is no evidence it will. On Friday the extent of the Parliamentary Labour Party's reaction to the Copeland catastrophe was a series of hand-wringing statements that 'the country needs Labour'.

But that is the point. The country has decided it doesn't. Voters see a party that has no coherent policy on Brexit. That has not had a coherent economic or fiscal policy for decades, and as a result has no coherent policy on public service provision. That adopts stances on defence, law and order and immigration that are not just incoherent, but overtly provocative.

And the country has decided something else.

Until Friday morning, Labour MPs believed that they had one thing to fall back on – their Northern safe zone.

Time and again I have been told: 'People in my area hate Corbyn but they hate the Tories even more. Ukip might be a problem. But they won't vote Conservative.'

Northern voters will vote Conservative. Corbyn has not just helped complete the toxification of the Labour brand, he has also begun the process of detoxifying the Tory brand, a process the Prime Minister fully intends to finish.

The virus is not on the doorstep, but is coursing through Labour's system. There is no antidote. There is no cure."
