UN chief highlights Ukraine concerns in Moscow visit

Today was the day the United Nations took its grievances about Russia's invasion of Ukraine directly to the Russian president.

The UN Secretary-General, António Guterres, told Vladimir Putin that his invasion fully contradicted the constitution of the UN charter, but insisted he was visiting Moscow as a "messenger of peace".

Also in the programme: An interview with a Russian member of parliament; we hear from the wife of an opposition activist jailed for speaking out about the war; and we discuss the future of Twitter - under Elon Musk.
