New Covid-19 variants

The UK variant of coronavirus is undergoing genetic changes. Tests on some samples show a mutation already seen in the South Africa and Brazil variants.
Our BBC medical correspondent explains the changes and what can be done to help stop the spread. And our regular medical expert, Dr Isaac Bogoch, will answer listener questions about the new variants, and new trials combining two shots of different vaccines.

Also on the programme, we head to Turkey where police moved onto the campus of Istanbul's Boğaziçi university to quell a student protest after the appointment of a new rector. We hear from some of those young people.
