SIR - I was amused to read in your in your report on Covid Track and Trace in Bradford (T&A August 22) of the proposed collaboration between the local authority and the “NHS” programme.

This is NOT the NHS. This is the out-sourced service to the private company Serco. Let the professionals, the local organisations, run this vital service. I know, I have worked with them. Not a penny more to Serco.

Dr Christopher Butler, Dock Lane, Shipley
