Reality Check: Have MEPs done 'proper jobs'?
The claim: MEPs have not done "proper jobs" that benefit the economy.
Reality Check verdict: It depends on your definition of a "proper job". Of the 14 MEPs who spoke on Tuesday, 13 have spent part of their careers outside politics. Five have worked in business or trade. Of these, four have started their own business, including Nigel Farage MEP.
Speaking at the European Parliament's first debate on the UK's vote to leave the EU, MEP and UKIP leader Nigel Farage told MEPs: "I know that virtually none of you have ever done a proper job in your lives or worked in business or worked in trade or ever created a job."
It was one of many tense exchanges throughout the session, which was marked by booing and shouting. The European Parliament passed a motion urging the UK to start the exit process by triggering Article 50 immediately.
But politics and heckling aside, what do we mean by a proper job? This accusation is usually directed at people who have spent the majority of their working lives in politics, whether as elected politicians, in think tanks, or as civil servants. Mr Farage is talking about people who worked in business and trade.
There are 751 MEPs in the European Parliament - too many to look at it in one article - so we've looked into the previous careers of the 14 who spoke at the session today.
Let's start with Marine Le Pen. She began her political career in 1998 as a regional councillor, but before that she practised as a lawyer for six years. She is trained in criminal law and also worked as the director of the Front National's legal service from 1998 to 2004.
Guy Verhofstadt spent his whole career in politics. He began as a city councillor in 1976 after studying for a law degree. He served as prime minister of Belgium from 1999 to 2008. He has also sat as a Member of the Chamber of Representatives and a Member of the Senate in his home country as well as on a number of company boards.
Martin Schulz, president of the European parliament, is a former bookshop owner. He completed an apprenticeship as a bookseller between 1975 and 1977.

Gianni Pittella held various local and national posts during his career in Italian politics, prior to moving to Brussels. He studied medicine and specialised in forensic pathology. His profile on the EU Parliament website states that he was employed doctor in medicine in the private sector, but only in 1979.

And what about Nigel Farage himself? He's the leader of the United Kingdom Independence Party (UKIP). He became a commodities trader in 1982 and was listed as company secretary for Farage Limited, a commodities broker, until 2011. It is currently in liquidation. The company wasn't big enough to list how many employees it had so we don't have a precise figure for the number of jobs he created.
He joined UKIP in 1993 and became leader in 2006. He was first elected to the European Parliament in 1999, and still holds the post.
