David Cameron and Nigel Farage faced public questions on the EU referendum in a live TV event.
The Prime Minister said leaving the EU amounted to quitting and we are not quitters, he said. Ukip leader Nigel Farage said being British meant not being bullied by anybody.
An audience member was sceptical about Cameron's deal with the EU and ability to reform the EU.
"Our membership is right for Britain," the Prime Minister said. "It helps us work with other countries to get what we want."
"We need to be in this organisation, fighting for British interests and for British jobs. I don't think we're quitters."
He added that Britain has a unique status in that there is a proposal to ensure that migrants coming to Britain need to work here for four years before gaining access to the welfare state.
