Responding to the launch of the test and trace system in England (see 4.45pm), the British Medical Association public health medicine committee member and former chairwoman Dr Penelope Toff has said:

Having a robust test, track and trace system in place is vital to being able to effectively prevent a second wave of infection and to ensure that we can safely ease out of lockdown.

What will be absolutely crucial is that the government can implement this effectively with all the components in place, so it can run at capacity.

Alicia Kearns, the Tory MP for Rutland and Melton, is another to criticise Cummings, while stopping short of calling for his departure. A statement posted on her website reads:

Over the weekend. I relentlessly pressed for more information to get the facts of what happened, I believed that was the least the British people were owed. On Monday, we received more of the information that residents had been calling for: I wish this information had been made available at an earlier time.

I do not support Mr Cummings' actions. I would not have done the same.
