Jeremy Corbyn will refuse to commit to cutting migration if he wins the General Election and will formally rule out leaving the European Union without a deal.
Labour’s draft manifesto says that the party believes in “fair rules and reasonable management” of migration but rules out “making false promises on immigration numbers”.
It commits to scrapping minimum income rules for the partners of non-EU migrants, making it easier for them to come to the UK.
The approach comes despite the fact that many voters in Labour’s traditional heartlands supported Brexit because they are concerned about the impact of uncontrolled migration from the EU.
Mr Corbyn’s manifesto also says that leaving the European Union without a deal is the “worst possible” option and would damage the economy and trade. It says that Labour will formally “reject no deal as viable”.
Theresa May has repeatedly warned the European Union that no deal is preferable to a bad deal. She has said that ruling out the option would undermine Britain’s negotiating hand.
The Labour manifesto also says it will “immediately guarantee” the rights of EU nationals living in the UK. The Prime Minister has refused to do so without securing an agreement that the rights of Britons living in Europe will be protected.
Labour says it will also guarantee a “meaningful vote” on the final Brexit deal in Parliament, despite concerns that doing so could be used to frustrate Brexit.
The manifesto says: “Labour recognises that leaving the EU with ‘no deal’ is the worst possible deal for Britain and would do damage to our economy and trade.
“We will reject ‘no deal’ as a viable and negotiate transitional arrangements to avoid a cliff-edge for the UK economy.”
Mr Corbyn has put a strong defence of migrants at the heart of its manifesto, hailing their “historic contribution” to Britain and accusing the Tories of “fanning the flames of fear”.
The Labour manifesto says: “The Conservative government has scapegoated immigrants to divert from for their own failings and have made bogus promises on immigration.
“When politicians fan the flames of fear it has real consequences on both recently-arrived and long-settled communities.
“We see this in the appalling rise in hate crimes, which shame us all. Labour understands the historic contribution of immigrants and the children of immigrants to our society and economy.
“Today, the National Health Service, our social care providers and private companies across many sectors depend on the labour of migrant workers.
“We value those workers and we will never denigrate them. We also understand the importance of more skills training for British nationals, whatever their colour or creed.”
The party says it will scrap current migration rules for those from outside the EU, which bars them from coming to the UK unless they earn £18,600.
It will instead replace it with an “obligation to survive without recourse to public funds”. “We do not believe family life should be protected only for the wealthy,” the draft manifesto says. Labour also vows to retain EU legislation on workers rights, consumer rights, environmental protections and equality law after Brexit.
The manifesto says: “A Labour approach to Brexit will ensure there can be no rolling back of key rights and protections and that the UK does not lag behind Europe in workplace protections and environmental standards in future.”
