South Africa mourns Desmond Tutu

As South Africa begins a week of mourning for Archbishop Desmond Tutu, we hear stories from people who met him. We also explain who he was, including his role in the anti-apartheid struggle.

We answer your latest questions on the coronavirus pandemic with the help of one of our regular expert guests, Professor Manfred Green from the University of Haifa in Israel.

All week, we’ll reflect on 2021 with some of the BBC correspondents who have helped us tell the story of the year. Today, with our Climate Editor Justin Rowlatt, we look back on floods, heatwaves and the Glasgow climate summit.
