Ed Miliband was given the chance to speak on his “life experience” outside of politics today while being grilled by students on live television.

But the crowd of first-time voters seemed unimpressed by his reel of credentials in the corridors of power, including working as an economic adviser to Gordon Brown and teaching economics at Harvard.

The Labour leader was speaking to young voters during a question and answer session on Monday at Facebook's London offices called Stand Up Be Counted: Ask The Leaders.

When asked what experience "outside of politics" he had to “indicate that [he] should be the one to represent the people of Britain”, he replied: “I've done a number of things which I think, I hope, are relevant to this.

“I was obviously an economic adviser to the Treasury. I think that’s important because how we change our economy is at the heart of the country.

“I've taught, I taught at Harvard University. I actually taught around government and economics.

“I think one of the things that did for me was actually the ability to be able, I hope, to listen and engage with people about what their issues are, what they’re interested in.”

The comments come after a series of failed attempts to look 'normal' including the bacon sandwich incident

The Labour leader went on to talk about his family’s background as refugees fleeing the Nazis and how that inspired him to enter politics.

“Why am I in politics, you might wonder? It’s because I think it makes a difference to our country,” he added.

“I was brought up by my parents to think ‘you’ve got a duty to leave the world a better place than you found it’.”

The session was part of Sky News’s “Stand Up and Be Counted: Ask the Leaders” pre-election event, where David Cameron and Nick Clegg will also appear.

Mr Miliband also spoke out against tax evasion, graduate unemployment and unpaid internships during the session.

He started his career after graduating from Oxford University as a researcher on Channel 4’s A Week in Politics before being recruited by Harriet Harman to her shadow department.

He was then promoted to work for Mr Brown, then the shadow Chancellor, before taking out to study for a masters degree at the London School of Economics.
