South Yorkshire MP John Healey has joined leading charities and businesses to form the End Youth Homelessness alliance.
The group aims to recruit new supporters and gain public support over the coming months to help raise awareness of the problems facing homeless young people - who number 80,000 across the UK.
Wentworth and Dearne MP Mr Healey said: “I felt it was very important to be involved in the alliance.
“Homelessness is an issue that has a huge impact on young people, adults and families in my constituency.
“Any attempt to tackle this has my full backing.”
The alliance involves a number of charities including Centrepoint, DepaulUK, Homeless Link, St Basil’s, Relate and Family Lives.
