Nationally, the data found that people living in the most deprived areas of England have experienced coronavirus mortality rates more than double those living in the least deprived areas.

For those deaths involving Covid-19 that took place between March 1 and April 17, the mortality rate in the most deprived areas was 55.1 deaths per 100,000 population.

By contrast, the rate was 25.3 deaths per 100,000 in the least deprived areas.

The data by the ONS also shows the Covid-19 mortality rate in the most deprived areas of England has been higher among men (76.7 deaths per 100,000 population) than women (39.6).

Nick Stripe, ONS head of health analysis, said: "General mortality rates are normally higher in more deprived areas, but so far Covid-19 appears to be taking them higher still."
