it criticised public health england's focus on health improvement topics such as obesity and binge drinking, arguing that these should be tackled by local nhs health teams. in august 2020 the telegraph welcomed the change, characterising phe as the quango "responsible for many critical failures over the course of this pandemic" that had to be scrapped. on 2 september 2020, more than 70 health organisations wrote to the government to express concern about the future of health improvement work under these changes. the appointment of lady harding as interim executive chair of the new body was criticised by health experts as she did not have a background in health, and because of her political position. the guardian quoted allies of hers who, in response, said that she had quickly learned after being appointed chair of nhs improvement in 2017 and that she had a record of "getting things done" while working in business. the timing of the reorganisation, during the ongoing pandemic response, was criticised by various health experts and other bodies, including the editorial in the bmj, the institute for government, the king's fund, and christina marriott, the chief executive of the royal society for public health. an editorial in the guardian compared it to "reorganising a fire brigade as it tries to put out a blaze" and said the decision had been made without proper consultation or scrutiny.
