The Guardian reports confidence in the official COVID-19 inquiry has been hit by the leaking of thousands of WhatsApp messages sent by Matt Hancock, who was health secretary in the early part of the pandemic.

The paper notes that Isabel Oakeshott, the journalist to whom Hancock gave access to his texts while they were co-authoring a book, was an outspoken critic of lockdowns, and says bereaved families groups are now calling for the public inquiry into the pandemic to be given more teeth and completed swiftly.
