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.
David Cameron has said remaining in the EU is Britain's best chance to thrive.
The prime minister said there was "a real consensus that we would be worse off if we leave", with many economic experts warning of the dangers of Brexit.
He admitted "forecasters don't always get it right", but added: "I don't remember a time when had such a consensus."
Mr Cameron said Britain could survive outside the EU. However, he said: "We could find a way, but in my view it's not the right way."
