The last leader of the Soviet Union, Mikhail Gorbechev, has died, aged 91. The former president opened up the Soviet Union but failed to prevent its collapse in 1991.

Praised in the West for being on the right side of history, he is viewed differently now in Russia, as the man who presided over the dissolution of the Soviet Empire.

Russia's President, Vladimir Putin said today that Mikhail Gorbachev has a huge impact on world history.

Also in the programme: we speak to a writer of Mr Gorbachev's famous Pizza Hut advert; and as a team from the nuclear watchdog, the IAEA, heads for Europe's largest nuclear power plant in Zaphorizhia, we hear from Ukraine's ambassador to the organisation.

The first grain from Ukraine in months reaches the Horn of Africa. It is the first vessel carrying Ukrainian grain to arrive in Africa since Russia invaded the country in February.

Also on the programme: After Monday's bloodshed, is Iraq heading for fresh elections? And a human rights group says a Saudi woman has been sentenced to forty-five years in prison for social media posts.
