New year, new idea: Dennis Holmes, an accident and emergency manager from the West Yorkshire Metropolitan Ambulance Service trust, on duty at one of two mobile medical centres set up in Leeds on new year's eve as a 'trial run' for the millennium celebrations. The centres, staffed by members of the St John Ambulance brigade with support from the trust, treated about 50 revellers, helping to relieve pressure on ambulance services and hospital casualty units. Trust chief executive Trevor Molton said: 'I think it went very well and was a good trial run for the millennium.' The mobile medical centre scheme is now likely to be run in other areas of West Yorkshire at busy times of year.
