The Guardian reports that homeless charities have been forced to turn away thousands of volunteers who wanted to help out during the festive period - saying they have been overwhelmed by the numbers who were keen to carry out tasks such as serving Christmas lunch.
The paper says reports of increasing homelessness has led to wider public awareness.
One volunteering boss suggests people should instead help when charities are less well-staffed - "A cold February evening at a night shelter isn't on people's minds because they've done Christmas", she concludes.
