Addressing the Progress conference, Barnsley East MP Dan Jarvis refers to Labour's "Clause Four moment" - when the party agreed with then-leader Tony Blair to drop a clause committing it to public ownership of industry from its constitution.

He claims that Labour must make even more fundamental changes.

Labour MP Dan Jarvis - who recently ruled himself out of the leadership race - is addressing the Progress conference.

He tells colleagues that "this is not a time to mourn" but to "reflect [and] renew".

But "we also need to ask tough questions of ourselves", he adds.

The Conservatives presided over "the slowest economic recovery in 100 years... vandalised our National Health Service... and failed in its core promise to balance the books", he says.

"Yet still we lost."

The Co-operative Group will continue funding the Co-operative Party - which has close ties to Labour - to the tune of around £1m a year, following a vote at its annual general meeting.

The Co-operative Party stands election candidates jointly with Labour.

Today's motion to approve political funding "not to exceed £1m per annum" was carried by 55.17% to 44.83%.

Chancellor George Osborne has been scathing about the Labour leadership contest, calling it "a farce":

The Labour leadership candidates taking part in the Progress hustings are asked: What do you say to people who feel they are being squeezed out and undercut by migrants, and left behind by technology?

Liz Kendall: "One of the mistakes of the last government was to be a bit too cavalier about the impacts of globalisation... [but] we can either seek to blame others for the problems we face... all we can say to people is 'We will give you the skills, knowledge, confidence, chances and choices to make a better life for yourself'... We cannot try and simply turn the clock back."

Andy Burnham: "We have to deal with it more upfront than that... We have haemorrhaged votes amongst C2s, DEs in the last decade... As a party we must always defend free movement, but... we shouldn't say it follows that we support freedom to claim."

Yvette Cooper: "Britain's long been an outward-looking country and we have to stay so, and we know how much we depend on the investment from Europe... We have to make sure the [immigration] system is controlled and managed so that it's fair."

Mary Creagh: "It is totally wrong that agencies are recruiting exclusively from abroad... I'm talking about the exploitation of people coming in... I think it's really important that we keep to the principle of free movement."

Tristram Hunt: "These are the huge challenges facing the future of the UK... Immigration has put pressure on wage rates... The uncomfortable truth is... [people who are being undercut] have to go up the value chain, and the state has to support [them]. The way you get through immigration questions is education and skills."

Labour leadership candidates are asked: how could you encourage a UK equivalent of Apple co-founder Steve Jobs? 

Tristram Hunt: "It begins with school and education, and it begins with creativity, and valuing creativity."

Liz Kendall: "The best ideas that I've seen in creating incredible new industries and companies come by bringing people from different backgrounds together."

Andy Burnham: "Take taxes off aspiration."

Yvette Cooper: "If we're really going to think about the Steve Jobs of the future... One of the questions has got to be: 'Why is it Steve Jobs, and not Stephanie?'"

Mary Creagh: "We need to make sure all of our towns and cities and villages are connected - the future is digital."

So what happened there in Glasgow? Basically, despite surviving a no-confidence vote today, Jim Murphy is quitting as Scottish Labour Party leader and he wants a new head in place by the summer. He wants to leave the party's top job with a plan for reform - he criticises the electoral college system used for electing a leader and replacing it with one member one vote.
