Conservative MP George Eustice explained the "menu of alternatives" put forward by the First Start Group of Tories which calls on the UK government to review its relations with the EU.
The menu would involve a renegotiation of powers over justice, employment rules, energy and agriculture - and lead to a referendum of the British people.
He was debating the future of Britain in or out of Europe with former Chancellor Norman Lord Lamont, UKIP deputy leader Paul Nuttall and ex-TUC general secretary Lord Monks.
