My Lords, test and trace is working to improve performance across all those areas, in particular through the community testing programme. Local directors of public health are playing a leading role in targeting testing to those parts of their local communities where it will have the greatest impact. In addition, all 314 local authorities in England have local tracing partnerships working with test and trace to improve performance in those areas.
My Lords, the noble Lord is correct that the Government allocated £22 billion to test and trace in the last financial year. As I said, more than 80% of that has been allocated to testing. He is absolutely right that we have sought opportunities to drive down costs where possible and free up resources. We have taken a number of steps to reduce costs, including through commercial negotiations with suppliers, which have released £2.2 billion of savings, and technological advancements. A further £6 billion of savings were achieved by lower demand, changing priorities and deferred activities during the national lockdown from December to March.
