President Putin warns against NATO expansion in annual news conference

President Putin talked for four hours - but did he reveal anything about Russia's intentions towards Ukraine? We discuss his comments with former NATO secretary general Jan de Hoop Scheffer. Also in the programme: US infectious diseases expert Dr. Anthony Fauci on what we know so far about the Omicron variant; and remembering Joan Didion, the American writer who has died, aged 87.
