“Under Jeremy Corbyn’s plan for unlimited and uncontrolled immigration, (net migration) could increase to over 840,000 people — more than the population of Liverpool — coming to the UK every year”
Conservative Research Department report
The claim was based on a motion passed at Labour Party conference calling for the party to “maintain and extend free movement rights.”
Full Fact pointed out that the policy had not been confirmed. In an interview with the BBC on 14 November, Jeremy Corbyn said the party’s priority was to secure immigration rights “for those that have legitimate settled status in the UK, that is family reunion.”
Full Fact added that the Tories’ methodology was based on “extreme assumptions” about how far Labour would extend free movement and many people would take advantage of it. It assumed the policy would apply to the whole world and it assumed migration would happen on a similar scale to that between the UK and new EU members such as Hungary. Concluding that there was no evidence to suggest the latter assumption was realistic, Full Fact concluded that the CRD’s methods were “not credible.”
The Conservatives’ net migration claim lacked any credibility.
