SOAP star Denise Welch lit up Newcastle last night as she switched on the city's Christmas illuminations. After a false start, the celebrity, who played barmaid Natalie Barnes in Coronation Street, flicked the switch and the city's streets came alive. Earlier in the day, the Derwentside-born actress visited Consett Civic Centre, where she met Snug, a theatre group made up of disabled and able-bodied children. Picture: CRAIG CONNOR
