In the notes, Sir Patrick called former PM Boris Johnson: “All over the place and completely inconsistent.”

He also criticised Mr Johnson’s “impossible flip-flopping” and “bipolar decision-making”, and in another entry referred to “chaos as usual” in Downing Street after a meeting on social distancing.

These personal notes have been used by Hugo Keith KC, and other inquiry counsel, to question ministers and other officials over Downing Street’s response to the pandemic and the culture at the time in Number 10.
