UKIP's Diane James denies scaremongering over immigration. But what would change if UKIP had its way? Ms James stumbles slightly before explaining her party's plans for a work permit system.

Instead of an EU migrant working in our public services, "why not have somebody who speaks our language?," she says. 

That prompts a sharp intake of breath from the audience. 

This is getting a bit messy - a young woman is trying to make a point about roaming charges and is getting interrupted a lot.

"This feels like I'm in the House of Commons here and it's prime minister's questions," she says.

One young man scores a hit with the audience with a call to stop all the name-calling and exaggeration.

"I have no idea what to do and I blame you lot entirely," he tells the panel of politicians.

Alex Salmond is back to his favourite theme of the night.

Project Fear in the Scottish referendum has been divided in two for the EU referendum, he says. 

"Leave the scaremongering behind," he says, and make a "positive case" for staying in the EU.

Project Fear won, points out Victoria Derbyshire. But the independence campaign made up a lot of ground, Mr Salmond hits back.

It was always going to come up - Liam Fox says the UK sends £350m a week to the EU. Alan Johnson is having none of it because the UK gets a rebate and EU money is spent in the UK. Mr Fox argues that it is about controlling the money - and being able to decide how it's spent.

  A row between audience members now - and quite a heated one - between Emily from Poole who is arguing to come out of the EU, saying the UK government can build more homes.

"The European Union are not some kind of scapegoat for your problems", another member of the audience tells her.

Emily from Poole says she wants to leave the European Union because of fears that her family will not have access to a council home because of pressure from migrants.

"We have a housing shortage - we should build more houses" says Alex Salmond, "not kick people out of the country".

The SNP's Alex Salmond - for the Remain campaign - says if we leave the EU it "would not be an apocalypse" - but people would have more chance of a good job "if we stay in".

Richard from London says the EU has stagnated economic growth and that it is independent countries - such as Singapore and Switzerland - which have the best growth.

A young woman from London says people coming from the EU are helping with Britain's economy.
