Here is a comment from Prescott.
It is not helpful to dismiss such comments with "He would say that."
The fact that such prominent people are expressing such criticisms of the party serve to show how deep in the mire Labour is.

"I've served under nine Labour leaders and fought 12 elections, with the majority of those years under a Tory government.
When I entered Parliament in 1970, Labour averaged 11million votes – or 40 per cent.

That fell to 30 per cent at the last election with eight million voting Labour. We've been as low as 25 per cent in some opinion polls.
So Labour has lost over three ­million votes over 45 years.
You can't put it down to any one leader. But if this decline continues, the chance of Labour returning to government is impossible.
During my 47 years in Parliament I have attended over a thousand Parliamentary Labour Party meetings as a backbencher and Deputy Leader. While they've always been boisterous, what was said in the room always stayed in the room.
Now I regularly see a minority of MPs texting journalists a negative running commentary of the meeting. But it wasn't helped that after losing Copeland to the Tories, the leader and two of his Shadow
­Cabinet members(Abbott and Chakrabati) failed to turn up.
One MP showed me a picture of the missing women – they were drinking wine in the Lords bar! No wonder their fellow MPs were ­furious. Labour, from the leader to every MP, has to get its act together or we're finished."
