The Barnsley Central MP, tipped as a challenger to Mr Corbyn, attended an event at the National Union of Mineworkers’ HQ in his constituency on Saturday.
A packed audience heard Tosh McDonald, president of train drivers’ union Aslef, lambast Labour MPs for failing to abandon the “failed New Labour experiment.”
Mr Jarvis, sitting on the platform, looked on awkwardly as Mr McDonald let rip into those who he said had abandoned Labour’s socialist roots and no longer represented the working class or the organised labour movement.
“We should be standing credible candidates in every seat. We can see how under Jeremy Corbyn Labour is getting back to what it should be,” he said to applause, in which Mr Jarvis took no part.
He added: “There is not a split in the Labour Party. There is a split in the Parliamentary Labour Party — people who do not recognise that the New Labour experiment lost us five million votes and a 100-seat majority.”
Six times Mr Macdonald’s speech was interrupted by applause from the enthusiastic audience and guests on the platform — except Mr Jarvis, who either remained motionless, or reached for a glass of water as the applause thundered.
After the event one ex-miner told the Morning Star: “Dan Jarvis must have a bladder like a barrel.”
But Mr Jarvis reluctantly rose to his feat when the conclusion of Mr McDonald’s speech was met with a standing ovation.
Mr Jarvis applauded once, when Mr McDonald attacked the Scottish National Party, and joined in half-heartedly as Mr McDonald received a standing ovation at the end of his speech.
The pointed speech came just days after Mr Jarvis fuelled rumours he is set to challenge Mr Corbyn following his talk to the Blairite think tank Demos.
He has also accepted two five-figure donations in the last two months from hedge-fund manager Martin Taylor and businessman Peter Hearn.
Mr McDonald slammed Labour MPs who attack Mr Corbyn in right-wing newspapers, and shadow ministers who chose to resign on television.
“I was watching TV and saw that John Reynolds had resigned. He was shadow railways minister,” he said. “I am president of [railway union] Aslef and I didn’t know him.
“Neither did any member of our national executive committee.”
He also called for more working class and trade union MPs to replace the “eggheads” dominating the current Parliamentary Labour Party.
He said: “We need them but we have enough eggheads, we don’t need any more. We have solicitors, and we need them, but we don’t need any more.
“If you are just a careerist, looking for a shadow cabinet job for your portfolio, you should not be there.
“If you are a Labour MP you should be talking to the workers, representing the workers. I’m talking about the people who will not give up the failed New Labour experiment.”
Mr McDonald was delivering the annual lecture in memory of David Jones and Joe Green, Yorkshire miners killed on the picket line during the strike against pit closures of 1984-5.
