Britain's new homeless: Banker sleeps rough in park

Britain is in the grip of a housing crisis of a sort not seen before, where even the most unexpected people are losing their homes.
Kevin Browne is an investment banker. He moved to America and ran his own firm until the crash in 2008. His company went bust and his marriage fell apart.
He eventually lost his home and returned to England on a flight paid for by a charity. BBC Panorama met him last summer while he was sleeping rough in a park in Croydon.
Panorama: Britain's Hidden Housing Crisis, BBC One, Thursday, 13 December at 21:00 GMT and then available in the UK on the BBC iPlayer.
