Russia Ukraine tensions continue

Western intelligence services believe up to 100,000 Russian troops are gathered near Ukraine's borders. Ukrainian authorities say Moscow could be planning a military offensive at the end of January. US officials however say it's not clear whether Russia's President Putin has made a decision. We ask people in both countries whether they are worried about escalations there.

Following claims of rule-breaking by members of Prime Minister Boris Johnson's ruling Conservative Party, the UK government has lost the previously ultra-safe parliamentary seat, North Shropshire. We hear reaction from UK voters and explain how by-elections work.

And, our regular coronavirus expert, Dr Megan Murray, answers questions sent in by our listeners.
