Jeremy Corbyn: Migration is a plus to our economy and many make an 'amazing contribution'
Freedom of movement is "generally good thing" and "migration is a plus to our economy", Jeremy Corbyn said.
The Labour leader stated his position on immigration as he reiterated his support for the Remain campaign ahead of the EU referendum.
Mr Corbyn told ITV's Peston on Sunday: "Those that work in our health service, make sure our health service survives are often people that have come to live in this country either from outside Europe or within Europe."
He said the free movement of people around Europe is "generally a good thing" but there was a "very important caveat".
Mr Corbyn believes it would make "good television" if he and David Cameron shared a stage during the EU referendum - although said it will not happen.
Asked if there would be any point in the pair sharing a stage during the campaign, Mr Corbyn said: "I don't think it would work. Do you think it'd work? It'd be good television but it's not going to happen, OK?"
After Boris Johnson's comparison of an EU superstate to efforts by Hitler to dominate Europe, Mr Corbyn said: "Boris Johnson has some very odd interpretations of history.
"I think he actually needs to take some lessons from Jacob Rees-Mogg because he's a better historian than Boris Johnson."
The Labour leader said he blames Conservative cuts for shortages in schools, hospitals and services.
Despite his brother Piers saying Jeremy is "in his heart a Eurosceptic", Mr Corbyn emphasized his support for the Remain campaign and said he had made his position "very clear".
Asked about his brother's claims that he believes there is a chance he could vote Leave, Mr Corbyn replied: "He's a weather forecaster not a psychologist."
The Labour leader was also asked if he considered himself to be middle class.
