From the man heading up security for this summer's Olympics to a self-proclaimed "Bra Queen", we unveil the ambassadors helping us put together the Channel 4 Jobs Report.

C4 Jobs Ambaasadors.

How do we create 2.5 million jobs? As the Channel 4 Jobs Report looks for answers to the biggest question facing the UK economy, we've teamed up with a panel of experts from some of the most influential brands in the world of business.

The C4 Jobs Ambassadors will be on hand to share their skills and answer the key questions about job creation in Britain in 2012. There will also be opportunities to engage with them via our Facebook page: facebook.com/Channel4JobsReport

We're aiming to unearth positive stories about the state of the jobs market, while exploring the challenges faced by today's jobseekers.

Between them, our ambassadors are responsible for tens of thousands of employees in the UK jobs market.
