What happens if we left the EU and then rejoined?published at 17:40 British Summer Time 26 May 2016
Listeners have a lot of questions about the European Union and the UK's referendum on whether to leave or remain.
PM asked the BBC's Europe correspondent Chris Morris and Assistant Political Editor Norman Smith to answer a selection.
Norman Smith answers Brian Case's question: If the UK voted to leave the EU and then 10 years down the road there was another referendum, would we then have to abide by the rule of joining the single currency?
