Can mouthwash really 'kill coronavirus', and what was on Obama's 'Presidential Playlist'?

Mouthwash can kill coronavirus within 30 seconds of being exposed to it in a laboratory, a scientific study has found. The preliminary result comes ahead of a clinical trial into whether using over-the-counter mouthwash could to reduce the levels of Covid-19 in a patient's saliva. We speak to Professor Damien Walmsley, from the British Dental Association, who says the latest research from Cardiff University now joins a growing body of evidence that mouthwash can kill coronavirus. He explains how it works, and why the government should include dental hygiene in its anti-Covid messaging. 

Also, Barack Obama's revealed the 'Presidential Playlist' he says he used to get him through his time in the Oval Office. With tracks like Aretha Franklin's 'The Weight' and BB King's 'The Thrill is Gone' has he revealed what it's really like to be President? We talk to Professor John Street who has written a book on the connection between music and politics. He tells us how global leaders use their favourite tunes to help shape their public brand, and has anything like that Love Actually scene with Hugh Grant dancing in Downing Street ever really happened?
