"What role should the private sector play in the future of the NHS?" Alexander Quinn

Chris, Rothwell: Is this Question Time or the Jeremy Kyle Show? Russell Brand is a fool with loud mouth that is just trying to make a name for himself. Is he campaigning or the working class? If so, I feel embarrassed.

Joe, Brandon: Reducing immigration might not solve all our problems but it would help a great deal and improve our quality of life.

Conservative MP for Portsmouth North Penny Mordaunt calls for better border controls and remove financial incentives for people coming to the UK.

"They should contribute to the country, we shouldn't have to support them. We need to vet people coming into the country."

Boy George tweets: Best @bbcquestiontime ever!

Mary Creagh MP argues that in difficult times the country needs investment in public services. She points out that her father came from Ireland and worked hard.

BBC Question Time

Camilla Cavendish: 'I don't think anyone in this country wants to shut the door, but… people want a sense of control' #bbcqt

Camilla Cavendish says people are generally welcoming to immigrants but that most people want controlled immigration.

"Stand for Parliament. If you're going to campaign, stand!"

Another member of the audience criticises Nigel Farage and rebukes UKIP's policies. Temperatures are running high in Canterbury...

Mark Chazot, Faversham: There are a lot of clever people in politics but not many wise people. Russell Brand is like the court jester - funny but wise. This world needs more wisdom and less clever double-speaking politicians.

Henry, Norfolk: Please tell Nigel Brand that Australia has high turnout because it has compulsory voting and nothing to do with their politics.

"Since the financial crash, banker bonuses have exceeded £80 billion. George Osbourne campaigned to stop caps being placed on banker bonuses at the same time as there were austerity cuts against the poorest among us. We need to close tax loopholes that are exploited by big corporations. I've got money now, I've seen rich people. There's plenty of money out there, it's just not being distributed."

"Immigrants are not causing the economic problems and suffering we're experiencing. I enjoy seeing Nigel Farage in a boozer with a pint and a fag laughing off his latest scandals about breastfeeding or whatever. But this man is not a cartoon character. He ain't Del Boy, he ain't Arthur Daley, he's a pound-shop Enoch Powell and we've got to watch him."

BBC Question Time

Stephen Nickell, one of the leaders of the Office for Budget Responsibility, said the UK was not overcrowded. , external#bbcqt

Within urban areas, the ONS found that 1.1m of 23.4m households in England and Wales were overcrowded, external

"If you fly into Gatwick you will see lots of green spaces. However, if you have a country in which the population goes up as a direct result of immigration, what you find is not a shortage of green fields, you find a shortage of primary school places, you find a shortage of GP surgeries. We have fewer GPs per head than any other country in Europe today. You find congestion on the roads and the London Underground or wherever you go.

"You are constantly playing catch-up and the general quality of life for the mass of population goes down. In 1990 the population of this country was 55 million. It is now between 62 and 63 million and that is a massive increase."

"Is Britain really overcrowded?" Lynne O'Donoghue, retired civil servant

Charlie, London: The reason Russell Brand has 9 million Twitter followers is because he speaks sense. His comments on not voting resonated with me because it feels like a paradigm shift is needed.

Graham, Ramsgate: Nigel Farage is out of touch with no policies and riding on the poorly equipped alternatives in Tory/Lab/Lib Dem world. Let's see the US-style ballot papers with "none of the above" added. Then we'll see how good these so-called politicians really are.

Dan, Oxford: "It was said earlier that the reason people vote is because of hope and optimism. I would argue that in fact many people vote to ensure tyrannical parties don't get in, to counter their chances of being elected or re-elected. I for one will be voting Labour, purely to ensure the NHS isn't destroyed rather than having much faith in Miliband."

Ant, Rhyl: "More hecklers in the QT audience than in the Commons!"

Sue, Colchester: "Just hope Farage gets his policies into Parliament and let's all save Great Britain before it's too late."

"There are pieces of theatre in parliament and some fantastic debates," she tells the audience in Canterbury.

Even though she disagrees with a lot of what politicians from across the political spectrum say, "their hearts are in the right place".

Another member of the audience says people are fed up with the "Punch & Judy" style of political debate but also raises concerns over the voting system.

Automatically attacking political opponents is a real problem, he adds.
