Brother of archbishop is 'miracle worker' in Uganda
He has been hailed as a "bona fide rock star of evangelical Christianity" and has pledged to perform miracles. "Pastor Robert is preaching today," said a woman at the entrance to the 10,500-seat auditorium, where his flock must pass through airport-style security, complete with metal detectors and armed police.
The buzz is for Robert Kayanja, the younger brother of the second most senior figure in the Anglican Church, John Sentamu, the Archbishop of York.
Back in his native Uganda, Mr Kayanja has become one of the richest and most famous evangelical preachers. But while Archbishop Sentamu preaches in the stately calm of York Minster, his brother's performances have a different flavour.
