4. The people behind the numbers

The scale of the pandemic means it's difficult for the stories of many of those who die with the virus to be heard. On 12 April alone, at least 1,174 people died in England and Wales. Reporter Alice Cuddy tells the stories of seven of them.

5. 'Captain Tom' becomes colonel on 100th birthday

After raising more than £29.5m for NHS charities by walking 100 laps of his garden, Tom Moore is being made an honorary colonel by the Army. As well as a 100th birthday card from the Queen - and 140,000 more from other well-wishers - he was celebrated with an RAF flypast. Follow the latest on our live page.
