Britain's main opposition Labour Party announced on Tuesday (Wednesday NZ Time) it will reject Conservative Prime Minister Theresa May's proposed divorce deal with the European Union when it comes to a vote in Parliament and might even support a new Brexit referendum.
Delegates in the conference hall responded with noisy applause, with some jumping to their feet.
The study said that, if immigration is not part of the negotiations with the EU and the United Kingdom is deciding its future system in isolation, there should be no preference given to citizens from the European Economic Area, which includes the present 28 EU countries, as well as Iceland, Norway and Lichtenstein.
May has a working majority of just 13 in the 650-seat parliament and divisions in her own party over Brexit mean that Labour could have a crucial role in deciding whether the deal gets through.
Labour leader Jeremy Corbyn backed his Brexit spokesman, but declined to say which way he would vote in a possible second referendum because "it depends what the question is".
"The priority, though, isn't the arcane wording of motions, it's about jobs and living standards".
"The EU was a social democratic movement, and it was a good idea, but after the financial crash, it chose to bail out the banks at the expense of the people", Brexit supporter Les Thomas said at a protest against a second referendum.
In his keynote speech at the conference, he said: "We will vote down a blind Brexit".
He said: "That must include campaigning for a public vote. Keir Starmer was setting out one of the many possibilities; there's many junctures in this process", he said. "We need to extend Article 50", she said at a fringe event. "It's about stopping a destructive Tory Brexit and fighting for our values".
The government has also said that the role of the European Aviation Safety Agency (EASA) which monitors and regulates aircraft safety in the EU, will be transferred to the UK's Civil Aviation Authority (CAA).
Mrs May said she remained confident of securing a withdrawal agreement with the European Union, but the government would continue to plan for the possibility of no deal.
More than 100 local Labour constituency parties sent motions to Liverpool calling for the party to evolve its position over Brexit.
Chief executive of the Food and Drink Federation Ian Wright said the technical notices laid bare the grisly prospect of a no-deal Brexit, including chaos at the ports, serious disruption to food supplies and more administrative burdens on the food and drink industry. "It's about fighting for our values and about fighting for our country". "Values that can bring our country back together".
