Britain's left-wing political leader slammed President Trump during a speech at the Glastonbury festival in the south of England.

Labour MP Jeremy Corbyn said the festival's 81-year-old founder, Michael Eavis, "brought the spirit of great messages" through his event.

"There's a message on that wall for President Donald Trump," Corbyn said, pointing to a distant barrier around the farm.

"And, you know what it says? Build bridges, not walls," Corbyn boomed.

Corbyn, 68, objected to Trump's planned Mexican border wall and immigration reforms, saying England is better off with migrants from the east.

"Everyone we meet is unique. Don't see them as a threat, don't see them as an enemy - see them as a source of knowledge... friendship and inspiration," Corbyn said.

Of the immigrants to the United Kingdom, Corbyn said, "They must all stay and they must all be part of our world."

Corbyn also discussed his message of income inequality.
