Labour Leader Jeremy Corbyn has called on the government to respect the vote in the Lords amending the Article 50 legislation to protect the status of EU Nationals living in Britain.
In Yorkshire and the Humber alone, almost 7,000 EU nationals work in social care or the NHS.
The government has signalled its intention to seek to overturn the Lords' amendment in the Commons.
Jeremy Corbyn is continuing to coordinate EU-wide efforts by socialist parties to protect the rights of UK citizens living in the EU and EU citizens living in the UK.
The Labour Leader said:
"EU nationals, who have made their lives here, are welcome here, their rights should be guaranteed. Labour voted for it in the Commons; we beat them in the Lords.
“And now it is time for Theresa May to guarantee the rights of all EU nationals in this country. People are not bargaining chips.
“Over 50,000 EU nationals, including 10,000 doctors, work in our NHS.
“Our NHS needs all their talents.”
