Boris Johnson is set to announce £3bn extra winter funding for the NHS to help prepare for a second wave of the virus and to relieve seasonal pressures on A&E.
The funding will allow the NHS to continue using additional private hospital capacity and maintain the Nightingale hospitals until the end of March.
Mr Johnson is also expected to confirm plans to increase testing capacity to half a million antigen tests a day by the end of October to bolster the test and trace system.
In the wake of a dire warning of the consequences of Covid-19 rebounding, Downing Street said the funding will allow extra hospital capacity while allowing routine treatments and procedures to continue.
