Samaritans

The hub at Anglia Ruskin University (ARU) in Cambridge will be manned by students who will respond to messages solely on the charity's new online chat service.

The charity marks the date to remind those in need that its helpline will be open 24 hours a day, seven days a week, over the festive period.

Volunteers at the Jersey branch will be among 1,500 volunteers nationally answering calls from people struggling on Christmas Day.
