Hundreds of thousands of people are officially homeless. Now, with unique access, reporter Datshiane Navanayagam goes behind the scenes inside two homeless hostels in London to reveal the increasing number of people who are in work and homeless, unable to afford expensive inner-city private rents. She draws on her own experience of being homeless and uncovers how a low-wage economy based on zero hour contracts is leaving some people with no alternative other than to sleep on the streets. Datshiane talks to housing charity Shelter about new statistics that lay bare the intense personal anguish and embarrassment felt by those who are working but homeless.
