In astonishing scenes for a music festival, an estimated 135,000 Glasto revelers congregated at the Pyramid stage to watch Corbyn give a rousing 20 minute speech before U.S. rap duo Run the Jewels took to the stage.
Corbyn made the remarks during a speech he delivered at England's famous, huge Glastonbury Festival on Saturday.
After stepping out to cheers, he thanked Glastonbury founder Michael Eavis for setting up the festival, describing it as "a place where people come together and achieve things".
Chants of "Corbyn, Corbyn" began as the festival gates opened at Worthy Farm at 7am on Wednesday and have continued ever since. There's a message for president Donald Trump. "Build bridges, not walls".
Corbyn told the left-wing newspaper the Daily Mirror that it was "ludicrous" to believe the Conservatives' minority government could survive, and that his party "will challenge this government at every step and try to force an early general election".
Talking about the election, he said "the elites got it wrong", adding: "That politics that got out of the box, is not going back in any box".
Building a wall on the US-Mexico border to stop the influx of refugees and undocumented migrants coming from Central and Latin America was a hallmark of Trump's presidential campaign.
"The young people who got involved in politics for the first time are fed up with being, denigrated, fed up with being told they don't matter, don't participate..."
And in a long, hope-filled speech the Labour Party leader revealed the inspiration behind the Labour election "For the many, not the few" campaign slogan.
"Shake your chains to earth like dew, which in sleep had fallen on you".
They easily outnumbered those for the biggest names on the musical bill - Radiohead, Foo Fighters and Ed Sheeran - and the chant "Oh, Jeremy Corbyn" rang round the world's biggest greenfield festival.
Taking festivalgoers on a tour of their hits including Best Of You, Monkey Wrench, Learn To Fly, These Days, My Hero and All My Life, the band were accompanied by chants of "10 more songs" and "three more hours".
The Labour leader addressed a huge crowd on Saturday afternoon (24 June) ahead of U.S. rap group Run The Jewels' performance.
