It is an honour to be appointed as Cabinet Secretary and Head of the Civil Service. Over these few months of working on the Covid response, I have seen how much hard work is being done by the Civil Service to support the government and our country through unprecedented times. It is a privilege to come into this role to lead a Service that is working day in, day out to deliver for people right across the country.
