“It would be a managed thing on the basis of the skills required,” he said of his
party’s future immigration policy. “What there wouldn’t be is
whole-scale importation of underpaid workers from central Europe in

Pressed on how his party would restrict immigration,
Corbyn said: “You prevent agencies recruiting for jobs like that, you
advertise for jobs in the locality first … It would be on the basis on
the economic need and skills required. The need for nurses is huge …
we have to be sensible about this.”
