David Cameron and Nigel Farage went head-to-head for their respective Remain and Leave campaigns in an EU debate on ITV.
Farage said he had been "demonised" for his views on immigration while Cameron said there were "good and bad ways" to handle immigration but he didn't back a "Little England" stance.
They took questions from the studio audience of 200 in the event moderated by ITV News presenter Julie Etchingham moderating.
The pair spent the day in London encouraging voters to register before tonight's (7 June) midnight deadline. Cameron urged the electorate to not "sit on the sidelines" while Farage unveiled a poster claiming his opponent wanted "what was best for the EU".

That's all folks...
The live blog has come to an end but stay with IBTimes UK for reaction and updates from Westminster.
Steven Woolfe MEP, Ukip's migration spokesman, said Farage's patriotism shone through.
"Nigel came out as a man that believes in Britain, who believes in the strength and opportunities the country would have leaving the EU.
"He believes that we could trade with the world, have a more fair and ethical immigration policy that treats the Commonwealth and those in the EU equally compared to someone like Cameron, who kept repeating the same mantra that we are a weak country, that we would be a feeble country and we would be lesser country by leaving the EU.
Speaking to IBTimes UK's Ian Silvera, energy secretary Amber Rudd said Cameron was right to focus on the economy.
"I don't think you can talk about the EU without talking about the benefits to people's everyday lives.
"What matters to people are jobs, are prices, are investment in our hospitals and in our schools so it is linked to the economy and it would be misleading to separate out these issues. It's right that [the prime minister] brings it back to people's everyday lives, which is attached to the economy.
"Immigration is important, there are many other issues which are important, but the most important thing about our membership of the EU is access to this extraordinary large single-market which gives us prosperity."
And that's the end of that. In the immediate aftermath it looks like Cameron, who looked pretty pleased with himself, won that one. Farage was on the defensive almost immediately during his exchanges, especially when pushed on Ukip's record on ethnic minorities.
Stand out moments included the prime minister admitting the EU was "frustrating" but that Britain was in a better position to push with reform from inside the EU. Farage meanwhile called for a return of British passports "so we can check anyone else coming in".
Cameron: This is a vote of British people...what I have said is that I will accept your instructions. I wan't people to focus on the choice of Farage and job losses or the extraordinary alliance [supporting Remain].
If we leave we will see our economy suffer...the British thing to do is to stay in and fight for reform.
Cameron: I don't want European Parliament to have more power.
Does Brussels need reform? Yes. Is it frustrating? Yes...but you have to ask yourself are we stronger and safer in?
Cameron: You hear a lot of talk about patriotism: I love this country with a passion....I do worry about a second Scottish independence referendum.
Sometimes it makes me mad, it is frustrating...but walking away would damage our country.
Cameron: I have not made forecast on immigration because of extraordinary times.
Cameron: I think we do have special status in EU. We don't have Euro, kept borders out of ever closer union.
Things I secured really do help us. We are safeguarded and can't be discriminated against...If we leave the reform ends.
Being on the outside looking in with our faces pressed against the window is no position for the fifth biggest economy.
Uniquely in Britain you have to work for four years and pay into the system before you have full access to benefits.
Cameron: Stronger economy from being in EU funds NHS.
We should think about 50,000 foreign nationals working in NHS.
Cameron: We want to live in country called Great Britain but in a European Union without ever closer union.
Obviously the control of immigration is an important issue and one of the ways we control it is to train people here to do the jobs that are delivering the British economy.
A good way to control immigration is paying in [tax] before you get out [benefits].
I think biggest risk we can take is to pull out of EU/single market and damage jobs and the economy.
People do not want Little Britain of Nigel Farage.
Here's the PM...
Cameron: We can survive outside the EU but can we thrive.
There would be a hit to economy, jobs, wages and prices in shops [if we left]
There are 500m people in the single market and with less access the economy will be smaller...The experts are right
If you cut yourself off from your most important market you will be at a disadvantage
And that is the end of Farage's questions. The Ukip leader was pushed on the economy, immigration, security and sovereignty as well as recent divisive comments.
Farage: I take this very simple view. Migrant policy has led to up to 5,000 Jihadis coming into EU in last 15 months...we have a very real problem.
As a sovereign nation we cooperate with friends and neighbours just like we do with America.
On World Trade Organisation - we have no vote on it! We are sometimes asked to leave the room.
We live in an inter-dependent world but the point of the referendum is this is a vote to get independence so we can make own laws with our parliament with our own courts.
EU is "done for" it is a "catastrophe".
Farage: We see reports that say EU migrants pay more tax than they take out...Lets agree with House of Lords that on economic terms its about equal.
The real truth is that population is rising at number that we need to measure quality of life and not just GDP...Population here will rise 80m by 2040. We need to build new house every 4 minutes night and day to cope with the current numbers.
Farage: Just calm down there [to female audience member asking about Cologne-style attacks comment]...What I said is that Cologne is huge issue and Angela Merkel made a mistake.
Young single males have settled in Germany who have different attitudes to women....I do believe in balanced border controls and I do believe Germany made a mistake
I take strong pro-Commonwealth view. Bad mistake to turn back on that for EU project.
If we have Australian-style points system rather than an open door to 508m people it will actually be better for black people
Farage: It is wrong, wrong, wrong for decent hard working families to have their living standards decline by 10% in the last 10 years.
Farage: We British, we're better than that, we're not going to be bullied by anybody, least of all the unelected Jean-Claude Juncker
Farage starts by saying 25 years ago the government was backed by expert economists - including David Cameron in the Treasury - to join the Exchange Rate Mechanism. He called the decision was "stone bonkers".
He then says how experts 10 years later said the UK should join the Euro, adding "thank God we didn't join"
The Ukip leader says "Once we've divorced ammicably we will continue buying cars" ie trade will continue
Here we go...
And its Farage up first
'Fate of the UK rests in voters' hands'
With ITV about to kicks things off, Stephen Kinnock tells Ian Silvera in the Spin Room that the very existence of the UK is at stake at the referendum:
"We are not suffering at all on the Remain side by the polls being close because what's really important is that we get our people out to vote and you wouldn't want any sense of complacency.
"I think what these polls show is that it's going down to the wire and that's good because it will drive our vote out.
"They've [Remain] got over a fortnight to save the UK because the UK would split up if we were to leave the EU.
"The urgency of that is going to be clear. It's really important people understand that and register to vote before the deadline at midnight tonight."
And this was Vote Leave's:
