It is his breach of the 'stay at home' rule that is being referred to. I think he was in a public space, a park, and not wearing a mask.
I should think doctors and nurses who are dealing with patients with the virus are not impressed by the SoS Health and Social Care.
He is a hypocrite -
'On 5 April 2020, Hancock threatened to ban all outdoor exercise in the UK in response to COVID-19 if people did not follow social distancing rules, saying "So my message is really clear. If you don't want us to have to take the step to ban exercise of all forms outside of your own home then you've got to follow the rules and the vast majority people are following the rules.'
'April 2019, Hancock, who had previously said the NHS would face "no privatisation on my watch", was criticised for allowing 21 NHS contracts worth £127 million to be tendered.'
