Over 57,000 children are set to wake up homeless in London on Christmas Day.
The charity Shelter says thousands of families are living in B&Bs or other temporary accommodation and the situation is getting worse.
Sharon Thomas has more.
Campbell Robb, Shelter's Chief Executive, is very worried about homeless families, especially at Christmas.
More than 57,000 children in London will wake up homeless on Christmas Day, housing and homelessness charity Shelter has warned today, enough to fill 254 primary schools in the region.
Shelter is highlighting the figures to launch its new campaign to raise awareness of the plight of homeless families in the area this Christmas, whose numbers have increased steadily over recent months.
Seventeen of the 29 London boroughs that supplied data will each have more than 1000 homeless children living in temporary accommodation.
Of particular concern is the increase in families forced to live in B&Bs in London, which has almost doubled in the last year.
