Republican presidential candidate Donald Trump says he wants to end the automatic right to citizenship for all children born in the United States.

All children born in the US – even if their parents are illegal immigrants – get citizenship under the constitution. Other measures he outlined would include raising visa fees to pay for a wall along the Mexican border.

Immigration is a central plank of Mr Trump’s campaign to be the Republican contender in next year’s election. “They have to go,” he told NBC.

A tough deportation policy was needed, he said, because “there’s definitely evidence” of crimes linked to immigrants living in the country illegally.
