Widnes College Christian Union - possibly the smallest CU in the world.
Both members meet in a shabby classroom every Tuesday lunchtime for prayer and Bible study, led by their FE (further education) CU staff worker, Martin Povey. 'Not exactly the cutting edge of campus-based evangelism', you might be thinking.
Except that recently, the bunch of 'A' level philosophy students who have their afternoon lesson in said classroom have been coming early to eat their sandwiches and discuss Christianity, turning the otherwise tiny CU meeting into a kind of evangelistic symposium.
