A Harrow synagogue is raising money for vulnerable people in the former Soviet Union by holding a Sleep Out event.
Northwood and Pinner Liberal Synagogue is encouraging people to join in by camping out tonight.
The event will take place at the Green Lane synagogue from 8pm.
Those taking part will celebrate Havdalah, a religious ceremony which marks the end of Shabbat, and sing songs around a campfire, led by Rabbi Aaron Goldstein.
Entering the event costs £10 and all participants are expected to raise a minimum of £70 in sponsorship.
The money raised will be used to provide winter relief food packages for people in the former Soviet Union.
